Hypothesis: To investigate if the application of different protocols of active recovery promotes difference in reducing Heart Rate (HR) in Post-Exercise (PE). This was a prospective, randomized trial of patients undergoing Exercise Testing (ET) and applied to two different protocols of active recovery. They were divided into G1 with recovery of 1.5 mph/2.5% and G2 40% of the speed and slope of the peak in the PE. Variables were evaluated pre-test and intrinsic to the TE. We compared the recovery of FC 1 and 2 min in the PE. Statistical analysis used the chi-square test, Student's t test and considered p<0.05. We analyzed 939 patients and 852 selected for randomization. Were allocated to G1 403 patients with mean age 47.86±14.31 years, 53.35% female and G2 with 449 patients with mean age 48.56±14.23 years and 51.7% were female. In the analysis of HR recovery of first (22.00 Vs. 23.57; p = 0.315) and second (36.17 Vs. 37.70, p = 0.06) minutes, G1 and G2 did not obtain differences. The use of different models of active recovery, applying fixed workload of 1.5 mph/2.5% slope or individually in 40% of the workload of the peak stress does not alter the recovery of HR in first or second minutes in the PE.

However, it has not been completely established if this fact is also observed within our community. Objective: To determine the most prevalent form of heart failure (HFpEF or HFrEF) and whether the prevalence of HFpEF is higher in the community. Methods: This is a cross-sectional study conducted with patients clinically diagnosed with HF who were seen in community-based health care centers from January to December 2005. Echodopplercardiograms were performed for all patients. The form of HF was stratified according to the presence of abnormalities and the shortening fraction observed on the echodopplercardiogram. Results: The study evaluated 170 patients (61.0 ± 13.3 years of age), most of them women and elderly. HFpEF was the more prevalent form of HF (64.2%, p<0.001), affecting mostly elderly women (62%, p = 0.07), whereas the opposite condition, HFrEF, was observed mostly in elderly men (63.6%, p = 0.07). Patients with no HF represented one-third of the cases (27.6%). HFrEF patients had more lower-limb edema, coronary disease, diabetes, chronic renal failure, higher Boston scores and hospital readmissions. Use of alcoholic beverages and smoking were also more common among HFrEF patients. Conclusion: HFpEF is the most prevalent form of HF in the community especially among elderly women, whereas HFrEF affects mostly elderly men and is associated with greater clinical severity, main risk factors and no changes in lifestyle. Despite the signs and symptoms of HF, this condition was not confirmed for one-third of the cases.

In our field, the association of MS in stable chronic HF patients has not been established. Objective: To determine the prevalence of MS in relation to gender and HF type in patients treated at a Primary Care Facility. Methods: Between January 2005 and August 2006, 144 patients were included in a cross sectional study. An echocardiogram, using the modified criteria of the EPICA study, was performed to determine whether or not the patient had HF, and of which type. Statistical analysis was conducted using the software SAS™ System, version 6.04, and statistical significance was established as 5%. Results: MS was observed in 111 patients (77%), of which 73 (66%) were females: odds ratio (OR) 0.195-(confidence interval-CI = 0.08-0.46) and p< 0.0001. HF was identified in 102 patients (71%) with a great correlation between females and the presence of MS: 51 patients (65%); OR 0.116 (CI = 0.36-0.37) and p < 0.0001. Among the HF patients, 61 (42%) presented HF with preserved systolic function and 41 (29%) with systolic dysfunction; p= ns. HF with preserved systolic function was associated with the presence of MS in 53 (87%) of the 61 patients, p = 0.022. Conclusion: In our community, MS is closely related to HF with preserved systolic function and to the female gender.

Analysis of Risk Factors for In-Hospital Mortality Purpose-To study the epidemiological, clinical, therapeutic and evolutive aspects of endocarditis in a group of patients aging 12 to 20 years-old (mean 15.5). Methods-Thirty-three consecutive patients (14 males, 19 females) admitted with infective endocarditis were retrospectively studied. Results-Infective endocarditis mortality was 42%. Rheumatic heart disease was the predominant underlying condition in 63% of patients. Congenital heart disease (24%) and cardiac prosthesis (12%) were the other affections involved. The majority of patients (78%) were in functional class III and IV, with more deaths than the 22% who were in functional class I and II (p=0.01). Staphylococcus aureus was the most frequently isolated agent (42% of the positive blood cultures, followed by Staphylococcus viridans, 21%). Multivariate analysis identified total leukocyte count above 10,000/mm 3 and functional class, both at admission (p=0.01 and p=0.004, respectively), and the occurrence of embolic complications (p=0.03) as independent predictors of in-hospital mortality. Conclusion-Rheumatic heart disease remains, as in adults, the main predisposing factor for infective endocarditis in adolescents, and S.aureus is, like in children, the leading agent. Mortality is high and functional class at hospital admission, embolic complications and leukocytosis are independent predictors of in-hospital mortality.
