Treadmill exercise testing in a middle-aged Jerusalem population sample. The Jerusalem Lipid Research Clinic Prevalence Study.

We studied determinants of the exercising physical capacity of 1,640 subjects (1,043 men and 597 women) using the Bruce protocol as modified by Sheffield. These participants represented a sample of parents of 17-year-old adolescents living in Jerusalem. Apparently healthy participants underwent a graded treadmill exercise test (88% of the men and 87% of the women). Exercise was terminated when the subject achieved a heart rate of 85 to 90% of the predicted maximal heart rate or could not continue for other reasons, mainly fatigue or weakness. Exercise performance was assessed according to time on the treadmill. On univariate analysis, duration of exercise was related in both sexes to age, country of origin, reported physical exercise, resting heart rate, systolic and diastolic blood pressure, body mass index and plasma lipids and lipoproteins. In multivariate analysis, time was related to age, body mass index, heart rate and habitual physical exercise in both men and women, and to systolic and diastolic blood pressure in men only. Cigarette smoking and plasma lipid levels were not independently related to time on the treadmill in either sex. Ethnic differences were observed.

[Experimental quantitative evaluation of the cardiac pump in function].

Experimental technique has been developed that makes it possible to change left ventricular after exercise on a wide scale during one beat at an intact circulation. The relationship between the maximal blood flow rate and left ventricular systolic pressure at permanently filled ventricle and inotropic state has been shown close to linear. This relationship (exercise characteristics) can be described by two parameters: maximal systolic blood pressure at blood flow and maximal blood flow ab zero peripheral resistance, and can be used for the assessment of the cardiac pump function.

[Chronic obstructive bronchopneumopathy, mitral valvulopathy and global cardiac insufficiency].

The case of a 61 year-old man is presented. This patient had a rheumatoid arthritis and a cardiac failure. Echocardiography and catheterization revealed a mitral valvulopathy, biventricular dysfunction and conduction abnormalities. Pericardial disease was also present. Differential diagnosis lead to the clinical diagnosis of rheumatoid non constrictive pericarditis, rheumatoid myocarditis, rheumatoid endocarditis and idiopathic calcification of the mitral valve. Anatomo-pathologic findings consisted in rheumatoid pancarditis.

Transatrial atrioventricular valve testing in the beating, fully loaded heart.

A detailed technique is described to safely inspect visually the function of the atrioventricular (mitral, common atrioventricular, or tricuspid) valve in the beating, fully loaded, but not ejecting left or right ventricle. The heartbeat is reestablished while the ascending aorta is kept cross-clamped and air from the ascending aorta is vented out. The left or right ventricle is filled via a 6-mm internal diameter tube derived from the arterial return line. To allow filling of the right ventricle for tricuspid valve evaluation, the pulmonary artery is snared down in addition.

Urinary albumin excretion--a predictor of risk of cardiovascular disease. A prospective 10-year follow-up of middle-aged nondiabetic normal and hypertensive men.

To study how the risk of cardiovascular disease changes with increasing levels of urinary albumin excretion (UAE), we prospectively studied a random sample of 120 49-year-old men with a wide range of blood pressures. Based on diastolic blood pressure (DBP), the subjects were divided into normotensives (DBP < 90 mm Hg; n = 21), borderline hypertensives (DBP 90 to 94 mm Hg; n = 30), mild hypertensives (DBP 95 to 104 mm Hg; n = 45) and moderate to severe hypertensives (DBP > 105 mm Hg; n = 24). None had been previously treated for hypertension or had secondary hypertension, diabetes mellitus, or other cardiovascular diseases at baseline. Heart and kidney function and metabolic and hormonal variables were with beta-blockade, diuretics, or hydralazine. The cardiovascular morbidity during 10 years of follow-up was studied. The hypertensives were treated with beta-blockade, diuretics, or hydralazine. The cardiovascular morbidity during 10 years of follow-up was studied. The 19 subjects who developed cardiovascular disease had significantly higher baseline UAE than the group that did not (median value 16.6 mg/24 h; range 3.5 to 73, and 9.7 mg/24 h, range 0 to 308, respectively). UAE correlated to systolic blood pressure (P = .0115) and DBP (P = .031), but not to smoking behavior or serum cholesterol. The risk of cardiovascular disease was associated with UAE and smoking independently of blood pressure (P = .001 and P = .015, respectively), and the risk increased continuously with increasing UAE. The initial UAE thus emerged as an efficient and independent predictor of cardiovascular disease in middle-aged hypertensive and normotensive men. UAE appeared to be a stronger predictor than blood pressure and serum cholesterol.
