Se comunica la experiencia adquirida en el diagnóstico, seguimiento y tratamiento de la hipertensión arterial pulmonar (HAP) y de la HP tromboembólica crónica (HPTEC) de la policlínica de HP del Hospital Maciel. Métodos: se analiza una cohorte de 15 pacientes (2009-2011). Se estimaron la clase funcional (CF), la prueba de cami-nata de 6 minutos (P6M), la excursión sistólica del plano del anillo tricuspídeo (ESPAT) y la velocidad sistólica pico (Sm). La severidad hemodinámica fue estimada por CCD. Se definió respuesta vasorreactiva aguda (RVA) positiva por el descenso de la PmAP >= 10 mmHg, alcanzando un valor absoluto > 40 mmHg sin cambios o aumento del índice cardíaco (IC). Los datos se expresaron como media ± DS. Se empleó el test de t student pareado para ...

Does early coronary artery bypass surgery improve survival in non-ST acute myocardial infarction?

Lack of evidence exists regarding the optimal timing for coronary artery bypass graft (CABG) surgery after non-ST myocardial infarction (NSTEMI). While some authors address the importance of the timing of surgery alone, others take into account the extent of myocardial damage. The question addressed was whether early or late CABG surgery improves hospital mortality and cardiovascular events after NSTEMI in stable patients. Using a designated search strategy, 459 articles were found, of which seven represented the best available evidence. All of these studies were level 3 (retrospective cohort studies). Studies could be divided into those which assessed CABG outcome based on preoperative cardiac troponin I (cTnI) level as a measure of the extent of myocardial damage and those which considered only the timing after myocardial infarction. Outcome measures included short-term survival, hospital mortality, length of ho...

We report the experience in the PH diagnosis, follow-up and treatment (groups 1 and 4 of DanaPoint)of the PH polyclinic of the Hospital Maciel. Methods: we analyzed a cohort of 15 patients (p) (2009-2011). We estimated the functional class (FC), the six-minute walk distance (6MWD), the tricuspid annulus plane systolic excursion (TAPSE) and the peak systolic velocity (Sm). The hemodynamic severity was estimated by RHC. Acute vasoreactivity (AVT) positive response was defined as a decrease in mPAP≥10 mmHg, reaching an absolute mPAP≤40 mmHg with an unchanged or increased cardiac index (CI). Data were expressed as mean±SD. Student t test and Kruskal-Wallis test were used to compare the specific treatment effects and for multiple comparisons, respectively,with a p<0.05. Results: me...

In the last few years, multidisciplinary management programs have been developed to improve its management. Yet, some patients take advantage of these programs, whereas others do not. Methods: Several demographic, medical, and social variables were evaluated as contributors to dropout after enrollment into a multidisciplinary heart failure program using a nested case-control design. A total of 14 patients and 42 controls were interviewed using a standardized questionnaire. Possible associations were explored by means of # 2 Mantel-Haenszel test and a binary logistic regression model. Results: The only significant factor associated with dropout was social isolation. Patients who lived alone, without family support, had a significantly greater dropout risk (odds ratio, 12.5; 95% confidence interval, 1.35Y11.6). Conclusions: For patients who live alone, an individualized approach may be better than a multidisciplinary management program, but this hypothesis should be investigated in future studies.
