The case files of 4,456 medical admissions in 1975--1976 at Ahmadu Bello University Teaching Hospital, Kaduna, Nigeria, included 354 cardiovascular patients. The most common causes were hypertension (45.5%), cardiomyopathy (20.6%) and chronic rheumatic heart disease (14.4%). The mean age of hypertensive and cardiovascular patients was lower than in Europe. The majority of hypertensive patients suffer from essential hypertension. Congestive cardiac failure is the commonest complication of hypertension and cardiomyopathy. Rheumatic valvular disease with mitral incompetence is frequent and sometimes severe in young people. Other cardiovascular diseases included pericardial disease, bacterial endocarditis, cor pulmonale, anaemic heart failure, congenital and syphilitic heart disease. Coronary heart disease was only encountered in non-Africans. Cardiovascular mortality in hospital was high (20%).

Most cardiovascular problems in pregnant women arise from the complications of preexisting chronic conditions (e.g., rheumatic and congenital heart disease) and hypertensive vascular disease. Regular supervision of these patients is essential to detect incipient pulmonary congestion or disturbances of cardiac rhythm. Even if the pregnancy has been uncomplicated, hospital admission 1-4 weeks before the due date is recommended to ensure optimal conditions for labor. Vaginal delivery at term with adequate sedation and use of forceps to shorten the 2nd stage of labor is the perferred mode. Induction of labor may be indicated in hypertensive vascular disease or in cases where adjusting or discontinuing drug therapy calls for precise timing of delivery. Eisenmenger's disease and primary hypertension are potential medical indications for pregnancy termination. The distribution pattern of organic heart disease encountered in pregnant women has changed in the past 20 years, with a decrease in rheumatic and an increase in congenital heart disease. The incidence of chronic rheumatic heart disease in pregnant women fell from 3.5% of all deliveries at Newcastle General Hospital in 1942-51 to 1.1% in 1962-71. Acute pulmonary edema in mitral stenosis is currently a major risk during pregnancy. There is no optimal stage of pregnancy for valvotomy, nor evidence that this procedure induces miscarriage in the early weeks. Pregnancy has become less hazardous in severe forms of congenital heart disease as more patients with these disorders have undergone cardiac surgery prior to pregnancy. Pregnancy is not believed to have any effect on the longterm course of rheumatic heart disease. Patients with aortic stenosis, coarctation of the aorta, primary pulmonary hypertension, Fallot's tetralogy, Eisenmenger's syndrome, and surgically untreated cyanotic lesions require special attention during pregnancy. The outlook for women who become pregnant after an acute cardiac infarction episode depends on the functional state of the heart at the time of pregnancy and the presence or absence of angina pain. There has been a gradual decline in perinatal mortality, especially in cases complicated by rheumatic heart disease.

All autopsies on Black patients who died of heart disease at Baragwanath Hospital were examined for the years 1959, 1960 and 1976. The commonest form of heart disease encountered in South African Blacks is undoubtedly hypertensive heart disease and by far the majority of these cases are of essential hypertension. There appears to have been a slight rise in the incidence of hypertension. Rheumatic heart disease is extremely common, and affects young people, who often have advanced valvular lesions by puberty. The incidence of idiopathic cardiomyopathy does not seem to have altered materially, although there has perhaps been a slight drop, which may be accounted for by the tendency of clinicians to place cases of congestive cardiac failure with mild hypertension in the hypertensive group rather than in the idiopathic cardiomyopathy group. There was a significant alteration in the incidence of myocardial infarction; in 1959 and 1960 these cases comprised less than 1% of all cardiac deaths but in 1976 they comprised nearly 12%. There has also been a dramatic fall in the incidence of cardiovascular syphilis.

The author examined 1,149 patients with cholecystitis, 90% of them had calculous and the others had non-calculous forms of the disease. Atrial fibrillation (AF) was found in 63 (5.48%) patients, which was combined in most cases with ischemic heart disease (IHD), essential hypertension (EH), and rheumatic heart disease concomitant of cholecystitis. In 12 cases with CF organic changes of the heart were not found. Eight patients has transitory AF for some years. In determining the indications for operations on the biliary tract in individuals with concomitant AF the author assigns importance to graded physical loading. In the group of 63 patients with AF 43 underwent surgical treatment for cholecystitis with a favourable outcome. The author claims that AF in combination with IHD, EH, and rheumatic heart disease is not a contraindication for surgical treatment of cholecystitis. In cases of transient AF the biliary tract should be examined more frequently because AF may be one of the signs of the biliary-cardiac syndrome in such patients. A history of thromboembolic complications and AF which are relieved with difficulty may be contraindications for operations on the biliary tract.
