Prevalence of hypertension and subtypes in an Indian rural population: clinical and electrocardiographic correlates.

The aims of this study were to determine the prevalence of hypertension (systolic > or = 140 and/or diastolic > or = 90 mmHg) and its subtypes such as borderline isolated systolic hypertension (systolic > or = 140, diastolic < 90 mmHg), definite isolated systolic hypertension (systolic > or = 160, diastolic < 90 mmHg), isolated diastolic hypertension (systolic < 160, diastolic > or = 90 mmHg) and definite hypertension (systolic > or = 160 and diastolic > or = 90 mmHg or hypertensives on treatment) in a rural population of a developing country. We have conducted a total community cross-sectional survey in a rural population of western India. 3148 persons (1982 males and 1166 females), aged > or = 20 years were examined in a cluster of three villages in Rajasthan.

Influence of cessation of smoking on long term mortality in patients with coronary heart disease.

Cessation of smoking in patients with coronary artery disease (CAD) has shown variable results. The long term mortality in patients of coronary heart disease (CHD) who quit smoking following diagnosis of their disease has been variable. We have analysed the long term effects of cessation of smoking on mortality in a cohort of 173 patients with CAD and compared the mortality of this group with 299 nonsmokers and 52 current smokers.

Influence of mild to moderate treated hypertension on 9-11 year mortality in patients with pre-existing coronary heart disease.

Hypertension is a known risk factor in the genesis of coronary artery disease. However, the effect of pre-existing hypertension on the long-term mortality in patients with established coronary heart disease is not clear. The present cohort study analysed the influence of baseline mild to moderate treated hypertension in cases of known coronary heart disease with cardiac mortality as end point.

Total cholesterol and mortality in patients with pre-existing coronary artery disease.

Background: A positive correlation exists between serum cholesterol levels and cardiovascular mortality. However, the role of serum cholesterol in persons with pre-existing coronary artery disease is not clear.

Methods: A cohort of 524 patients with coronary artery disease was divided into four groups based on the total serum cholesterol values.

Prognostic value of profound ST segment depression during treadmill stress test in coronary heart disease: nine years follow-up study.

To define the prognostic significance of profound ST segment depression (greater than or equal to 3mm) during exercise test, 106 patients of definite coronary heart disease enrolled in a prospective study were followed for up to 9 years. Group A (56 patients) had profound (greater than or equal to 3mm) ST segment depression (3.56 +/- 0.
