[Effect of myocardial revascularization on asymptomatic ischemic episodes].

Purpose: To evaluate the effect of coronary artery bypass graft surgery (CABG) on ischemic asymptomatic episodes (IAE).

Methods: Twenty eight males (means age 57.3 +/- 9.

[Cardiopulmonary exercise test in the evaluation of healthy elderly men].

Purpose: To study methodological aspects and results of cardiopulmonary exercise tests in elderly.

Methods: Twenty-five men (mean age 65 +/- 5 years) performed a cardiopulmonary exercise test using a bicycle ergometer and a progressive continuous work load increase protocol was employed. A computadorized system (2001 CAD/Net System-MGC), which includes a gas analyser and a pneumotacograph, was used for on line monitoring of oxygen and carbon dioxide expired fraction and also of pulmonary flow.

[Prevalence of primary dyslipidemia in subjects with and without family history of coronary disease, based on the reference values of the "National Cholesterol Education Program" (NCEP)].

PURPOSE--To compare the prevalence of primary dyslipidemia in 2 groups, based on NCEP guidelines: a) first degree relatives of revascularized patients and b) hospital employees without family history of coronary heart disease (CHD). METHODS--1162 subjects aged over 20 years, were divided in two groups: G Fam consisted of 312 women and 221 men, mean age 30.8 years, siblings, brothers or sisters of revascularized patients (under 55 years old); G Serv consisted of 425 women and 204 men, mean age 30.

[Ergospirometry as a method for predicting the clinical course of ischemic, Chagas and idiopathic myocardiopathy].

Purpose: To compare and evaluate the modifications variables obtained through spyroergometry in groups of patients with ischemic cardiomyopathy (IS), Chagas' disease (CH), and idiopathic cardiomyopathy (ID). To study tolerance to anaerobic conditions of patients from the above groups who died.

Methods: A study was carried with 50 male patients, 10 of which were found in normal conditions whereas 40 presented cardiomyopathy with compensated heart failure.
