An assessment of the anatomical factor in cor pulmonale in emphysema.

The morbid anatomical factors in the production of right heart hypertrophy and failure in emphysema have been reviewed with reference to 44 cases studied by standard histological methods and by post-mortem pulmonary arteriography. The most important factors in raising the pulmonary vascular resistance in these cases are considered to be vascular deformity and pressure by the emphysematous spaces on the adjacent branches of the pulmonary artery. Precapillary bronchopulmonary arterial anastomoses may be of importance in those cases where areas of localized bronchiectasis are present. Intimal fibrosis of the pulmonary arterioles, destruction of the pulmonary vascular bed, and thromboembolic phenomena were thought to be of only minor importance in the production of cor pulmonale in emphysema.

Ischemic heart disease and pulmonary ventilatory function.

The results of spirometric examinations on 4, 331 Israeli male civil service employees, aged 45 years or more, were analyzed according to the presence or absence of certain aspects of ischemic heart disease. Vital capacity was lower in individuals with a previously history of a heart attack, in those with definite or suspected angina pectoris and in those with ECG evidence of myocardial ischemia, probable or possible myocardial infarction, left bundle branch block or nonspecific T wave changes in subjects without these findings. The differences were small, but statistically significant. Vital capacity was lower in subjects with a recent history of a heart attack (within three years) than in those whose heart attack had occurred more than three years prior to the examination. The ratio of forced expiratory volume in the first second to forced vital capacity was not significantly different between individuals with or without a past history of heart attack, angina pectoris or ECG evidence of coronary heart disease.

Cardiomegaly in Northern Zambia: clinico-pathological observations.

Massive cardiomegaly (heart weight above 400 g in females and 450 g in males) was studied in 26 Zambians examined post mortem. The aetiologies found were: hypertensive heart disease alone in six cases; hypertensive and alcoholic heart disease in two cases; alcoholic heart disease alone in five; alcoholic and pulmonary heart disease in one; alcohol with possible hypertensive heart disease in one. Eleven cases were classified as being idiopathic mainly due to lack of data and in five of these hypertension was suspected as being the cause. The series qualitatively represented the spectrum of non-rheumatic heart disease seen in patients admitted to the Central Hospital, Ndola, Zambia. Hypertension had a central role in the causation of massive cardiomegaly. Follow-up of several patients enabled observations on the cardiac effects of hypertension and alcoholism operating simultaneously and on the relationship between hypertension and congestive cardiomyopathy.

Outcome and risk factors in surgery of descending thoracic aneurysms.

In a series of 100 consecutive patients operated upon for aneurysmatic lesions of the descending thoracic aorta, the mean age was 52 +/- 16 years (male = 81, female = 19). There were 31 dissections (acute 10, chronic 21); 28 post-traumatic aneurysms (ruptured 5, acute 7, chronic 16); 22 arteriosclerotic aneurysms (ruptured 1, chronic 21); 11 thoracoabdominal aneurysms, 5 anastomotic aneurysms and 3 mycotic aneurysms. No symptomatic patient was refused. Preoperative risk factors were graded on a scale of 6 by counting 1 point for each of the following elements: central nervous system disease; heart, pulmonary, and renal disease; arterial hypertension, age greater than 60. In-hospital mortality and paraplegia for the whole series were 25% and 7% respectively. In acute dissection, the mortality was 6/10 patients versus 2/21 in chronic events. In post-traumatic aneurysms, mortality was 2/5 in ruptured, 2/7 in acute and 0/16 in chronic events. In arteriosclerotic aneurysms, mortality was 1/2 in ruptured and 6/20 in chronic events. In thoracoabdominal aneurysms, mortality was 5/11, in anastomotic 1/5 and in mycotic 0/3 patients. The mean number of risk factors in non-survivors versus survivors was significantly higher in acute dissection, chronic dissection, chronic arteriosclerotic aneurysms and thoracoabdominal aneurysms. Rupture and acute events are related to a high surgical mortality. Non-survivors appear to have significantly more preoperative risk factors.

Prevalence of selected chronic diseases in Israel.

BACKGROUND: Knowledge of the prevalence of chronic disease in the population is essential for health planners and providers. OBJECTIVES: To present the results of a concentrated effort by the largest health maintenance organization in Israel (Clalit Health Services) in order to develop a comprehensive register of chronic diseases. METHODS: In 1998, all 2,704 primary care physicians in Israel's largest health provider were requested to report on all patients with selected chronic diseases. In addition, all the filled prescriptions for medications relevant to the investigated diseases and all relevant hospitalization events were added to the database. Prevalence rates were calculated based on the reporting practices only (1,653 physicians responsible for a total of 1,409,725 adults). RESULTS: Hypertension (10.2/100), diabetes (6.1/100), hyperlipidemia (5.7/100), peptic ulcer (4.7/100) and ischemic heart disease (4.3/100) were the most prevalent. Females had significantly higher rates of hypothyroidism, psychoses, neuroses and malignancies, and lower rates of ischemic heart disease, chronic obstructive pulmonary disease, heart failure and asthma. Arabs had higher rates of diabetes mellitus and lower rates of ischemic heart disease, hypertension and hyperlipidemia than Jews. About 20% of the adult population had one or more of the selected chronic diseases. CONCLUSIONS: Differences in rates noted between physicians, not explainable by population characteristics, may reflect differences in the quality and delivery of health services. Rate differences between demographic subgroups call for further studies on the etiology, susceptibility and natural history of these diseases.

Conduit repair for complex congenital heart disease with pulmonary atresia or right ventricular outflow tract obstruction. Part II: early and late hemodynamic and echocardiographic findings.

The results are presented of 44 systematic cardiac catheterizations in 35 patients after successful repair of various types of congenital cyanotic heart disease using a conduit. The operations were performed from 1972 to 1981. The patients were followed from 6 months to 9 years, the mean interval between operation and catheterization was 2.5 years (4 weeks to 8 years). Different types of conduits were used: a Hancock conduit in 27 cases (1 replaced), an aortic homograft in 3 cases (all 3 replaced by a Hancock conduit), a Dacron tube with Lillehei-Kaster valve in 2 cases (1 replaced), a lonescu-Shiley conduit in 5 cases, a composite graft of pericardium and a Hancock valve in one patient (replaced) and a valveless Dacron tube in one patient. The total conduit gradient was differentiated in 43/44 investigations. For the Hancock conduit the mean proximal gradient was 9 mmHg, the valvular 14 and the distal 13 mmHg. Severe valvular stenosis of the porcine valve occurred in 3 patients. For the lonescu-Shiley conduit only early, but promising, results are available. Three of the 35 patients died late (2.5 and 4 years postoperatively); the deaths were related to severe additional lesions. Cross-sectional echocardiography was performed in 32 of the 35 patients. The latter does not appear to be a reliable method for the detection of valvular lesions so far, but is helpful for the diagnosis of proximal and distal obstructions of the conduit.
