regarding the high prevalence of hyperlipidaemia, which is one of the major risk factors of cardiovascular disease, and uncertain reports about the relation between periodontal disease and serum lipid profile, this study was conducted to assess this relation. the historical cohort study was conducted on 52 cases including 26 persons with chronic periodontitis as case group, and 26 healthy subje...

As a vigorous field of inquiry, the history and geography of disease, understandably in light of the events of recent years, is enjoying a renewed surge in interest. Now come Cambridge Press and Kenneth Kiple with a monumental new Baedeker for this field. It will be a touchstone for years to come. Even if the sterile debate between relativist and (the nearly vanquished) progressivists, along wi...

We examined the relationships among ventricular arrhythmias, left ventricular dysfunction, and mortality after the occurrence of myocardial infarction in 766 patients who enrolled in a nine-hospital study and underwent two special tests. Frequency and repetitiveness of ventricular premature depolarizations (VPDs) were determined by computer analysis of predischarge 24 hr electrocardiographic re...

T1HE recent emphasis on early surgical intervention for patients with chronic rheumatic valvular disease has made the need for basic data concerning the natural history of this conditioii of practical importance. Data regarding the natural morbidity of patients with chronic rheumatic heart disease in the third, fourth, and fifth decades of life are presented. This information should prove usefu...

The new concept of systolic myocardial stiffness was applied to the study of ejection mechanics in aortic valve disease. Frame-by-frame analysis of stress (a) and volume (V) was performed for two differently loaded beats in 26 patients who underwent simultaneous cineangiography and micromanometry: nine normal subjects, eight with isolated aortic regurgitation (AR), and nine with aortic stenosis...

The afterload-corrected end-systolic volume index (ratio of end-systolic stress to endsystolic volume index [ESS/ESVI]) was previously useful in predicting outcome in patients with mitral regurgitation undergoing valve replacement. Therefore we tested ESS/ESVI together with standard hemodynamic variables as possible predictors of outcome in 39 patients with various valvular lesions who underwen...

Patients registered by the 1971 Perth Coronary Register as having suffered a myocardial infarction were followed up for 9 years. The Register was a community-based study that used standard methods and criteria as part of a World Health Organization collaborative investigation. Of the 1078 patients studied, 77% survived the first 24 hr and 62% the first 28 days; 0.3% were lost to follow-up. For ...

Incidence and significance of pericardial effusion in patients with acute myocardial infarction (AMI) have not been established. To evaluate these issues, we studied prospectively 138 consecutive patients with AMI. An echocardiogram was obtained in each 1, 3, and 10 days and 3 and 6 months after admission. Fifty four patients with unstable angina and 57 without heart disease were studied as con...
