Few data are available on the familial recurrence of congenital heart disease (CHD), in particular, in a large group of patients with isolated osASD. The aim is to investigate the familial recurrence of CHD in up to third-degree relatives from a large sample of consecutively enrolled patients with osASD, taking into account the influence of degree of relatedness (as number of relatives). Methods and results From January 1998 to December 2002, we enrolled 583 patients with osASD and 408 healthy subjects, referred to our tertiary centre. We hypothesized that a positive family history required at least one relative with CHD to constitute a risk factor. In this model of analysis, the null hypothesis is a similar familial history between cases and controls. Among 583 patients with osASD, 109 (19%) had at least one relative with CHD. Among the 408 healthy subjects studied, only 23 (6%) had a family history of CHD. A familial recurrence of CHD was demonstrated in 72 of 312 (23%) patients with isolated osASD and in 37 of 271 (13.6%) patients with non-isolated osASD. Familial recurrence of isolated osASD was demonstrated in 22 of 312 patients (7%) with an isolated osASD and only in six of 271 patients (2.2%) with non-isolated osASD. The familial recurrence risk of isolated osASD in patients with isolated osASD was higher in sibs, especially in sisters (33.3%). Conclusion This study underscores the role of genetic factors in the determination of CHD, particularly osASD. Our results could represent the basis for further studies to calculate a 'value of family history' to adapt the familial recurrence to the real size of each family group. In this way, we could select families with a 'tendency' to develop CHD, particularly osASD. In these families, we could analyse the genetic pattern to establish abnormalities and the bases of CHD.

Significant and balanced PA growth following AD stenting has already been consistently reported in the literature. However, no data are so far available about the role of this approach in severe PA hypoplasia, which significantly impacts the risk of surgical repair. Pre-surgical angiographic PA evaluation was performed in 45 patients with confluent PAs submitted to neonatal AD stenting as palliation of CHD-DPC. PA growth was evaluated as Nakata Index and McGoon ratio as well as individual PA z-score changes, both in the whole population and according to the original vessel size (Nakata Index <100 mm(2)/m(2), Group I [n = 15] vs. Nakata Index >100 mm(2)/m(2), Group II [n = 30]). Control angiography was performed 7.5 ± 6.5 months (median 6 months) after duct stenting, showing significant and balanced PA growth. The Nakata Index increased from 143 ± 73 mm(2)/m(2) to 270 ± 88 mm(2)/m(2) (124 ± 118%, p < 0.0001); left PA z-score from -0.7 ± 1.7 to 1.0 ± 1.4; right PA z-score from -0.6 ± 1.3 to 1.2 ± 1.3 (p < 0.0001 for both comparisons). Group I showed a greater increase of global PA growth (Nakata Index increase 227 ± 141% vs. 72 ± 57%, p < 0.001) as compared with Group II. Final PA size did not significantly differ between the groups (246 ± 105 mm(2)/m(2) vs. 282 ± 78 mm(2)/m(2), p = NS). Percutaneous AD stenting is highly effective in promoting a significant and balanced catch-up growth of diminutive PAs, being therefore advisable in this subset of patients as a reliable alternative to surgical palliation.

However, there have been several reports in the literature of sibling recurrence of total anomalous pulmonary venous return (TAPVR). This is the first case report in the literature, describing mother to offspring recurrence of d-TGA. We describe two cases of non-syndromic CHD with mother to offspring and sibling recurrence. The first case is an antenatally diagnosed d-TGA on fetal echocardiogram at 25 weeks of gestational age in the offspring of a 30-year-old mother with d-TGA. The second case is a sibling reoccurrence of TAPVR diagnosed antenatally at 30 weeks of gestational age, with supradiaphragmatic TAPVR on fetal echocardiogram in a mother, whose first child was diagnosed with infradiaphragmatic TAPVR in infancy.

Cardiovascular involvement is characterised by transient pancarditis, in acute phase, while coronary illness, ranging from mild dilation to giant CAAs occurs late, rarely before the 10th day since fever onset. Here, we describe a peculiar case of KD, which occurred in a 4-month-old infant and presented with exudate cardiac tamponade and early giant aneurism of both the proximal right coronary artery) and the left circumflex coronary artery, in acute phase of the disease.

After birth, decrease of prostacyclins and prostaglandins concentration usually causes arterial duct closure. This process may be delayed, or may even completely fail in preterm infants with arterial duct still remaining patent. If that happens, blood flow by-pass of the systemic circulation through the arterial duct results in pulmonary overflow and systemic hypoperfusion. When pulmonary flow is 50% higher than systemic flow, a hemodynamic &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;paradox&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; results, with an increase of left ventricular output without a subsequent increase of systemic output. Cardiac overload support neuro-humoral effects (activation of sympathetic nervous system and renin-angiotensin system) that finally promote heart failure. Moreover, increased pulmonary blood flow can cause vascular congestion and pulmonary edema. However, the most dangerous effect is cerebral under-perfusion due to diastolic reverse-flow and resulting in cerebral hypoxia. At last, blood flow decreases through the abdominal aorta, reducing perfusion of liver, gut and kidneys and may cause hepatic failure, renal insufficiency and necrotizing enterocolitis. Conclusions Large patent arterial duct may cause life-threatening multi-organ effects. In pre-term infant early diagnosis and timely effective treatment are cornerstones in the prevention of cerebral damage and long-term multi-organ failure.

However, no data are so far available about the role of this percutaneous approach in promoting PA growth in the case of congenital heart disease (CHD) with completely duct-dependent pulmonary blood flow (CDD-PBF). Aim of this study was to evaluate the effect of AD stenting in this pathophysiological setting. PA growth was evaluated as Nakata index and McGoon ratio as well as individual PA z-score changes in 49 patients submitted to neonatal AD stenting according to their pathophysiology (CDD-PBF (n=15) versus multiple PBF sources (n=34)). Control angiography was performed 7.2±6.4 months (range 1-8, median 6) after AD stenting. In the whole population, significant and balanced PA growth was recorded (Nakata index+122±117%; left pulmonary artery (LPA) z-score +84±52%; right pulmonary artery (RPA) z-score +92±53% versus preprocedure, p<0.0001 for all ...

A potential cause of the conflicting findings regarding the effect of sex on this novel CAD risk factor is the limited ability of the studies, to date, to adequately control for the potential confounding effect of CAD familial predisposition. Our purpose was to evaluate the influence of sex on Lp(a) concentration in healthy young individuals by controlling for family history of CAD. In order to achieve our goal, we compared Lp(a) levels in pairs of brothers and sisters with a positive parental history of premature myocardial infarction (PHPMI).

The aim of this study among high school students was to test the hypothesis that factors related to smoking behavior could differ in early (14-16-year-old students, younger age group) vs. late (17-21-year-old students, older age group) adolescence. The smoking behavior of 910 students was evaluated by a questionnaire. Students were categorized on the basis of their lifetime smoking behavior as never, former, occasional and regular smoker. Data were analyzed using Student&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s t-test, chi-square test and multinomial logistic regression analysis. In multinomial logistic regression analysis, variables related to adolescents&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; smoking behavior for both age groups were: positive attitude toward smoking (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), illicit drug use (younger age group, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001; older age group, P = 0.003), smoking at home with parents (younger age group, P = 0.038; older age group, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001) and get drunk at least once (younger age group, P = 0.002; older age group, P = 0.026). In the younger age group, a significant association was also found between students&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; smoking behavior and having smoked a cigar at least once (P = 0.006) and smoking behavior of the best friend of the same sex (P = 0.001), whereas the relationship with the hours spent with friends of the opposite sex was of borderline significance (P = 0.058). In the older age group, other factors related to adolescent&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s smoking behavior were minimizing health consequences of smoking (P = 0.002) and the hours spent with friends of the same sex (P = 0.026). Our study demonstrates that, as adolescence advances, factors related to smoking behavior can vary.

However, arterial duct stabilization with a high-flexibility coronary stent could be an effective alternative in high-risk surgical candidates or whenever short-term pulmonary blood flow support is anticipated. On the basis of ductal origin and morphology, the stenting procedure can be performed from an arterial or venous route. Following arterial duct angiographic imaging, the stabilizing stent is chosen to completely cover the entire ductal length and dilated slightly less than the proposed surgical shunt. Procedural failure depends mainly on ductal tortuosity and ranges around 10% of cases. Morbidity and mortality are 8-11% and less than 1%, respectively. Mid-term fate of the stented duct is spontaneous, slow and progressive closure within a few months. Compared with a Blalock-Taussig shunt, stented ducts result in similar but more uniform pulmonary artery growth over a mid-term follow-up. Arterial duct stenting is a technically feasible, well tolerated and effective palliation in congenital heart disease with duct-dependent pulmonary circulation. It is advisable either in high-risk neonates or whenever a short-term pulmonary blood flow support is anticipated. The stented duct appears less durable than a conventional surgical shunt although it is highly effective in promoting a global and uniform pulmonary artery growth.

The aim of this study was to assess if healthy children, adolescents and young adults with a parental history of premature myocardial infarction (PHPMI) have increased Lp(a) levels and are at higher risk of elevated (>30 mg/dl) Lp(a) concentrations. Methods and results: One hundred fifty healthy children, adolescents and young adults with PHPMI (55% males; age 18 AE 6.7 years) and 150 age-(AE1 year) and gender-matched control subjects participated in the study. Concentrations of total plasma cholesterol, low-density lipoprotein (LDL)-cholesterol, high density lipoprotein (HDL)-cholesterol, apolipoprotein (Apo) A-I and B, triglycerides and Lp(a) were determined after fasting for 14 h. Participants with PHPMI had higher concentrations of LDL-cholesterol (107.9 AE 31.1 vs. 99.2 AE 28.7 mg/dl, p Z 0.01), Apo B (89.6 AE 26.4 vs. 82.8 AE 20.2 mg/dl, p Z 0.011) and Lp(a) (26.7 AE 34.0 vs. 19.2 AE 23.2 mg/dl, p Z 0.012) and lower HDL-cholesterol concentrations (47.9 AE 11.3 vs. 50.7 AE 13.9 mg/dl, p Z 0.038) than participants without PHPMI. Thirty percent of PHPMI positive subjects had elevated Lp(a) concentrations vs. 16.7% of PHPMI negative subjects (p Z 0.009; relative risk 2.14; 95% CI 1.23e3.73). In a conditional logistic regression analysis, Lp(a) concentration was significantly and independently associated with PHPMI. a v a i l a b l e a t w w w . s c i e n c e d i r e c t . c o m j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / n m c d Nutrition, Metabolism & Cardiovascular Diseases (2008) 18, 492e496

In this study we evaluated if PHPMI and PHH exert a different influence on carotid IMT and if their conjunction produces additive effects. High-resolution B-mode ultrasonographic evaluation of common carotid artery IMT was acquired from 48 subjects without PHPMI and PHH (22 males, 26 females; mean age 22.1±4.9 years; controls), 24 age- (±1 year) and sex-matched subjects with PHH without PHPMI (PHH-positive/PHPMI-negative subjects), 24 age- and sex-matched subjects with PHPMI without PHH (PHH-negative/PHPMI-positive subjects) and 24 age- and sex-matched subjects with both PHPMI and PHH (PHH/PHPMI-positive subjects). Lipid profile, resting blood pressure, smoking behaviour and body mass index (BMI) were also assessed. Carotid IMT was smaller in controls (0.41±0.07mm) compared to PHH-positive/PHPMI-negative subjects (0.47±0.10, p=0.023), to PHH-negative/PHPMI-positive subjects (0.54±0.11, p&lt;0.001) and to PHH/PHPMI-positive subjects (0.52±0.10mm, p&lt;0.001). Carotid IMT was greater in PHH-negative/PHPMI-positive (p=0.006) and in PHH/PHPMI-positive (p=0.031) than in PHH-positive/PHPMI-negative subjects. No difference in carotid IMT was evident between PHH-negative/PHPMI-positive and PHH/PHPMI-positive subjects (p=0.549). In the comparison among subjects using multiple regression analysis, only PHPMI, age and BMI were independently associated with carotid IMT. In healthy young subjects with PHPMI and/or PHH, carotid IMT is increased. PHPMI is a stronger predictor of increased carotid IMT than PHH. PHH in conjunction with PHPMI does not add any further detrimental effect on carotid IMT.

The distribution analysis of CHD in dizygotic twins could provide a useful tool to evaluate the role of genetic and environmental factors in the development of CHD. Dizygotic twins are siblings with different genes, growing together in the same womb. Aim of study: To investigate the occurrence of CHD in a large sample of dizygotic twins of nonconsanguineous healthy parents, comparing the data from non-twin patients. Methods: From January 1999 to December 2002, we enrolled 1743 CHD patients with, at least 1 sibling, and 66 pairs of dizygotic twins, referred to our tertiary center. The diagnosis of CHD was based on clinical and echocardiographic evaluation. Results: Considering only the sibling nearest in age for each non-twin patient the recurrence was 67/1743 (3.8%). Among these 67 patients, 35 (52.2%) had a sibling with the same or similar CHD. Conversely, considering all 1886 siblings, recurrence of CHD in the non-twin group was 70/1743 (4%). Of the 70 patients, 36 (36/70, 51.4%) had a sibling with the same suspected pathogenic mechanism of CHD. In 9/66 pairs of twins (13.6%), both siblings had a CHD. In the nine pairs of twins in whom both siblings had a CHD, the percentage of concordance (based on the suspected pathogenic mechanism) for CHD was 100% ( pb0.05). Conclusions: Our findings suggest that the higher recurrence and concordance of CHD found in dizygotic twins could depend on some poorly identified environmental risk during the pregnancy.

Group I showed a greater increase of global PA growth (Nakata Index increase 227 ± 141% vs. 72 ± 57%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001) as compared with Group II. Final PA size did not significantly differ between the groups (246 ± 105 mm(2)/m(2) vs. 282 ± 78 mm(2)/m(2), p = NS). Percutaneous AD stenting is highly effective in promoting a significant and balanced catch-up growth of diminutive PAs, being therefore advisable in this subset of patients as a reliable alternative to surgical palliation.

However, there have been several reports in the literature of sibling recurrence of total anomalous pulmonary venous return (TAPVR). This is the first case report in the literature, describing mother to offspring recurrence of d-TGA. We describe two cases of non-syndromic CHD with mother to offspring and sibling recurrence. The first case is an antenatally diagnosed d-TGA on fetal echocardiogram at 25 weeks of gestational age in the offspring of a 30-year-old mother with d-TGA. The second case is a sibling reoccurrence of TAPVR diagnosed antenatally at 30 weeks of gestational age, with supradiaphragmatic TAPVR on fetal echocardiogram in a mother, whose first child was diagnosed with infradiaphragmatic TAPVR in infancy.

Cardiovascular involvement is characterised by transient pancarditis, in acute phase, while coronary illness, ranging from mild dilation to giant CAAs occurs late, rarely before the 10th day since fever onset. Here, we describe a peculiar case of KD, which occurred in a 4-month-old infant and presented with exudate cardiac tamponade and early giant aneurism of both the proximal right coronary artery) and the left circumflex coronary artery, in acute phase of the disease.

After birth, decrease of prostacyclins and prostaglandins concentration usually causes arterial duct closure. This process may be delayed, or may even completely fail in preterm infants with arterial duct still remaining patent. If that happens, blood flow by-pass of the systemic circulation through the arterial duct results in pulmonary overflow and systemic hypoperfusion. When pulmonary flow is 50% higher than systemic flow, a hemodynamic &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;paradox&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; results, with an increase of left ventricular output without a subsequent increase of systemic output. Cardiac overload support neuro-humoral effects (activation of sympathetic nervous system and renin-angiotensin system) that finally promote heart failure. Moreover, increased pulmonary blood flow can cause vascular congestion and pulmonary edema. However, the most dangerous effect is cerebral under-perfusion due to diastolic reverse-flow and resulting in cerebral hypoxia. At last, blood flow decreases through the abdominal aorta, reducing perfusion of liver, gut and kidneys and may cause hepatic failure, renal insufficiency and necrotizing enterocolitis. Conclusions Large patent arterial duct may cause life-threatening multi-organ effects. In pre-term infant early diagnosis and timely effective treatment are cornerstones in the prevention of cerebral damage and long-term multi-organ failure.

However, no data are so far available about the role of this percutaneous approach in promoting PA growth in the case of congenital heart disease (CHD) with completely duct-dependent pulmonary blood flow (CDD-PBF). Aim of this study was to evaluate the effect of AD stenting in this pathophysiological setting. PA growth was evaluated as Nakata index and McGoon ratio as well as individual PA z-score changes in 49 patients submitted to neonatal AD stenting according to their pathophysiology (CDD-PBF (n=15) versus multiple PBF sources (n=34)). Control angiography was performed 7.2±6.4 months (range 1-8, median 6) after AD stenting. In the whole population, significant and balanced PA growth was recorded (Nakata index+122±117%; left pulmonary artery (LPA) z-score +84±52%; right pulmonary artery (RPA) z-score +92±53% versus preprocedure, p<0.0001 for all ...

A potential cause of the conflicting findings regarding the effect of sex on this novel CAD risk factor is the limited ability of the studies, to date, to adequately control for the potential confounding effect of CAD familial predisposition. Our purpose was to evaluate the influence of sex on Lp(a) concentration in healthy young individuals by controlling for family history of CAD. In order to achieve our goal, we compared Lp(a) levels in pairs of brothers and sisters with a positive parental history of premature myocardial infarction (PHPMI).

The aim of this study among high school students was to test the hypothesis that factors related to smoking behavior could differ in early (14-16-year-old students, younger age group) vs. late (17-21-year-old students, older age group) adolescence. The smoking behavior of 910 students was evaluated by a questionnaire. Students were categorized on the basis of their lifetime smoking behavior as never, former, occasional and regular smoker. Data were analyzed using Student&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s t-test, chi-square test and multinomial logistic regression analysis. In multinomial logistic regression analysis, variables related to adolescents&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; smoking behavior for both age groups were: positive attitude toward smoking (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), illicit drug use (younger age group, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001; older age group, P = 0.003), smoking at home with parents (younger age group, P = 0.038; older age group, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001) and get drunk at least once (younger age group, P = 0.002; older age group, P = 0.026). In the younger age group, a significant association was also found between students&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; smoking behavior and having smoked a cigar at least once (P = 0.006) and smoking behavior of the best friend of the same sex (P = 0.001), whereas the relationship with the hours spent with friends of the opposite sex was of borderline significance (P = 0.058). In the older age group, other factors related to adolescent&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s smoking behavior were minimizing health consequences of smoking (P = 0.002) and the hours spent with friends of the same sex (P = 0.026). Our study demonstrates that, as adolescence advances, factors related to smoking behavior can vary.

However, arterial duct stabilization with a high-flexibility coronary stent could be an effective alternative in high-risk surgical candidates or whenever short-term pulmonary blood flow support is anticipated. On the basis of ductal origin and morphology, the stenting procedure can be performed from an arterial or venous route. Following arterial duct angiographic imaging, the stabilizing stent is chosen to completely cover the entire ductal length and dilated slightly less than the proposed surgical shunt. Procedural failure depends mainly on ductal tortuosity and ranges around 10% of cases. Morbidity and mortality are 8-11% and less than 1%, respectively. Mid-term fate of the stented duct is spontaneous, slow and progressive closure within a few months. Compared with a Blalock-Taussig shunt, stented ducts result in similar but more uniform pulmonary artery growth over a mid-term follow-up. Arterial duct stenting is a technically feasible, well tolerated and effective palliation in congenital heart disease with duct-dependent pulmonary circulation. It is advisable either in high-risk neonates or whenever a short-term pulmonary blood flow support is anticipated. The stented duct appears less durable than a conventional surgical shunt although it is highly effective in promoting a global and uniform pulmonary artery growth.

The aim of this study was to assess if healthy children, adolescents and young adults with a parental history of premature myocardial infarction (PHPMI) have increased Lp(a) levels and are at higher risk of elevated (>30 mg/dl) Lp(a) concentrations. Methods and results: One hundred fifty healthy children, adolescents and young adults with PHPMI (55% males; age 18 AE 6.7 years) and 150 age-(AE1 year) and gender-matched control subjects participated in the study. Concentrations of total plasma cholesterol, low-density lipoprotein (LDL)-cholesterol, high density lipoprotein (HDL)-cholesterol, apolipoprotein (Apo) A-I and B, triglycerides and Lp(a) were determined after fasting for 14 h. Participants with PHPMI had higher concentrations of LDL-cholesterol (107.9 AE 31.1 vs. 99.2 AE 28.7 mg/dl, p Z 0.01), Apo B (89.6 AE 26.4 vs. 82.8 AE 20.2 mg/dl, p Z 0.011) and Lp(a) (26.7 AE 34.0 vs. 19.2 AE 23.2 mg/dl, p Z 0.012) and lower HDL-cholesterol concentrations (47.9 AE 11.3 vs. 50.7 AE 13.9 mg/dl, p Z 0.038) than participants without PHPMI. Thirty percent of PHPMI positive subjects had elevated Lp(a) concentrations vs. 16.7% of PHPMI negative subjects (p Z 0.009; relative risk 2.14; 95% CI 1.23e3.73). In a conditional logistic regression analysis, Lp(a) concentration was significantly and independently associated with PHPMI. a v a i l a b l e a t w w w . s c i e n c e d i r e c t . c o m j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / n m c d Nutrition, Metabolism & Cardiovascular Diseases (2008) 18, 492e496

In this study we evaluated if PHPMI and PHH exert a different influence on carotid IMT and if their conjunction produces additive effects. High-resolution B-mode ultrasonographic evaluation of common carotid artery IMT was acquired from 48 subjects without PHPMI and PHH (22 males, 26 females; mean age 22.1±4.9 years; controls), 24 age- (±1 year) and sex-matched subjects with PHH without PHPMI (PHH-positive/PHPMI-negative subjects), 24 age- and sex-matched subjects with PHPMI without PHH (PHH-negative/PHPMI-positive subjects) and 24 age- and sex-matched subjects with both PHPMI and PHH (PHH/PHPMI-positive subjects). Lipid profile, resting blood pressure, smoking behaviour and body mass index (BMI) were also assessed. Carotid IMT was smaller in controls (0.41±0.07mm) compared to PHH-positive/PHPMI-negative subjects (0.47±0.10, p=0.023), to PHH-negative/PHPMI-positive subjects (0.54±0.11, p&lt;0.001) and to PHH/PHPMI-positive subjects (0.52±0.10mm, p&lt;0.001). Carotid IMT was greater in PHH-negative/PHPMI-positive (p=0.006) and in PHH/PHPMI-positive (p=0.031) than in PHH-positive/PHPMI-negative subjects. No difference in carotid IMT was evident between PHH-negative/PHPMI-positive and PHH/PHPMI-positive subjects (p=0.549). In the comparison among subjects using multiple regression analysis, only PHPMI, age and BMI were independently associated with carotid IMT. In healthy young subjects with PHPMI and/or PHH, carotid IMT is increased. PHPMI is a stronger predictor of increased carotid IMT than PHH. PHH in conjunction with PHPMI does not add any further detrimental effect on carotid IMT.

The distribution analysis of CHD in dizygotic twins could provide a useful tool to evaluate the role of genetic and environmental factors in the development of CHD. Dizygotic twins are siblings with different genes, growing together in the same womb. Aim of study: To investigate the occurrence of CHD in a large sample of dizygotic twins of nonconsanguineous healthy parents, comparing the data from non-twin patients. Methods: From January 1999 to December 2002, we enrolled 1743 CHD patients with, at least 1 sibling, and 66 pairs of dizygotic twins, referred to our tertiary center. The diagnosis of CHD was based on clinical and echocardiographic evaluation. Results: Considering only the sibling nearest in age for each non-twin patient the recurrence was 67/1743 (3.8%). Among these 67 patients, 35 (52.2%) had a sibling with the same or similar CHD. Conversely, considering all 1886 siblings, recurrence of CHD in the non-twin group was 70/1743 (4%). Of the 70 patients, 36 (36/70, 51.4%) had a sibling with the same suspected pathogenic mechanism of CHD. In 9/66 pairs of twins (13.6%), both siblings had a CHD. In the nine pairs of twins in whom both siblings had a CHD, the percentage of concordance (based on the suspected pathogenic mechanism) for CHD was 100% ( pb0.05). Conclusions: Our findings suggest that the higher recurrence and concordance of CHD found in dizygotic twins could depend on some poorly identified environmental risk during the pregnancy.
