Nine patients examined by arteriography were shown to have mycotic aneurysms involving the thoracic aorta, subclavian artery, renal artery, middle cerebral artery, hepatic artery, and splenic artery. Patients presented with sepsis, chest pain, mediastinal mass, headache, hypertension, and intraperitoneal bleeding. Etiologic factors included endocarditis, septicemia, drug abuse, and poorly controlled soft-tissue infection. Most mycotic aneurysms were virulent processes with rapid progression and only three of the nine patients (33%) survived. Since mycotic aneurysms may be associated with rapid progression and poor prognosis, early recognition is mandatory.

An analysis was made of correlative factors which might be related to the angiographically measured extent of coronary artery disease in 140 patients. All patients presented with clinically important chest pain. Thirty-three had a normal coronary arteriogram. The extent of the atheromatous process was measured precisely at angiography by three different techniques. A coronary score, based on the percentage of luminal narrowing, was found to be best suited for the analysis. The most important contributory factors to the severity of atherosclerosis was duration of clinical history, number of previous myocardial infarctions, and male sex, but more specifically elevation of serum cholesterol and diabetes mellitus. Cigarette smoking, obesity, hypertension, a family history of atherosclerosis, and elevated serum triglycerides had a positive influence but this was not statistically significant.

The experience with 45 patients with lung abscess over a three-year period at the University College Hospital (UCH), Ibadan, is presented. This study confirms the rarity of this disease among Nigerian children and its prevalence in young adults in the third and fourth decades of life. The most common presenting symptoms were purulent cough, chest pain, fever, and life-threatening hemoptysis which was the sole indication for emergency operation in 14 out of 16 patients who were treated surgically. The predominance of these abscesses in the right lung, especially in the superior segment of the lower lobe, supports the fact that aspiration of infected material, following depressed level of consciousness, esophageal obstruction, foreign bodies, and oral sepsis form the major causative factors in patients with lung abscess. The frequent association of sickle cell disease, bronchiectasis, hypertension, and pulmonary aspergilloma contribute significantly to the morbidity and mortality attendant to this disease in our environment. Twenty-nine patients were treated medically with five deaths and 16 patients were treated surgically with six deaths. The high operative mortality (37.5 percent) in this series was due to the extreme emergency conditions under which these patients were operated.

To compare angiographically-determined coronary artery disease in diabetic patients with controls, 1,653 patients coming to cardiac catheterization were reviewed retrospectively to find 37 diabetic and 79 control patients matched for sex, age (+/- 3 years), and risk factors (hypertension, hyperlipidemia, and smoking). The severity of coronary artery disease was assessed using an angiographic grading system. The following results were obtained: 16 of 37 diabetic patients (43%) had three-vessel disease compared to 20 of 79 controls (25%). Seventy-six of 111 (68%) diabetic vessels were diseased compared to 110 of 237 control vessels (46%) (P less than 0.005). The total coronary score reflecting total extent of disease for diabetic patients was 371 (mean 10.0 +/- (SEM) compared to 594 for controls (mean 7.5 +/- 0.7, (P less than 0.01). Diabetic patients had a statistically similar number of diffusely diseased vessels as controls (28% vs 22%). There were only three of 76 diabetic vessels (4%) considered inoperable compared to seven of 110 (6%) control vessels. We conclude that diabetic patients with chest pain have more coronary artery disease than nondiabetics, but no more diffuse or inoperable disease.

Serial blood pressure recordings were taken for 72 hours in 112 patients with acute myocardial infarction and in 96 patients with cardiac ischemia, admitted to hospital no more than 6 hours after the onset of chest pain. During the first hour of admission 66 (31.7%) had a blood pressure recorded 160/100 or greater. By the sixth hour, without specific antihypertensive therapy, this number had fallen to 13 (6.3%). This fall was subsequently maintained with very similar trends for both acute myocardial infarction and cardiac ischemia. Such an early blood pressure fall in acute myocardial infarction may indicate that this is too labile a measurement to determine the need for, or efficacy of, antihypertensive therapy aimed at the preservation of myocardium. The hospital course and mortality rate of patients with acute myocardial infarction and early hypertension, as defined, did not differ significantly from the non-hypertensive group.

A review of eight cases of myocardial rupture following myocardial infarction confirmed the association of rupture with advanced age, a preponderance of females, hypertension, and physical exercise after infarction. In four patients, electrocardiograms recording the events of rupture showed further S-T elevation, supraventricular tachycardia, and conduction defects. One case of septal rupture showed increase in the amplitude of the P waves. The combination of these changes with sudden reappearance of chest pain, development or worsening of congestive cardiac failure with hypotension, and the appearance of a precordial systolic murmur should aid in the earlier diagnosis of this complication which may be amenable to surgery. Successful repair of rupture has been reported during the acute phase of infarction and after variable periods of delay.

The diagnosis of primary dilated cardiomyopathy depends on the recognition of a dilated poorly contracting left ventricle with increased end-diastolic and end-systolic volumes in the absence of a detectable cause. The diagnosis is made only after exclusion both of structural heart disease and of known causes of secondary heart muscle disorder. The natural history is still largely unknown and is probably as variable as the likely causes. The left ventricular disorder does not cause symptoms until heart failure supervenes except for occasional patients who develop an early atrial or ventricular dysrhythmia, conduction defect, chest pain or murmur of mitral regurgitation. This period of latency may be short, prolonged or even permanent since it is unlikely that all cases progess to the point of failure. A few patients recover normal or near-normal cardiac function. The interplay between high blood pressure, hypertensive heart failure and dilated cardiomyopathy is illustrated by patients who recover from heart failure to become hypertensive and vice versa and in current treatment with vasodilators and diuretics for patients at either end of the spectrum.

Serial study of 72-lead precordial ST-maps, SGOT, and SLDH was done in 30 cases of acute myocardial infarction. Infarct size was estimated by sum of ST elevation in all leads (sigma ST), number of sites showing ST elevation (NST), peak SGOT, and peak SLDH levels, and correlated with each other and with clinical features and hospital course. sigma ST correlated well with NST (r=0.92), but the correlations of sigma ST with SGOT (r=0.99) and SLDH (r=3.84) were better than those of NST with SGOT (r=0.22) and SLDH (r=0.53). There were close agreements between sigma ST and peak SGOT and peak SLDH except in the cases of non-transmural infarction, in whom smaller sigma ST suggesting small infract occurred with higher enzyme peaks indicating moderate or large infarct. Longer duration of chest pain, larger number of associated conditions (e.g. angina, hypertension, diabetes), complications (e.g. congestive heart failure, shock, arrhythmias) and mortality were associated with larger infarcts.

Myocardial infarct extension after the acute event was defined as a second reise in the myocardial isoenzyme of serum creatine kinase (CK-B) after the initial return of CK-B to normal values. In 43 patients with acute myocardial infarcts, CK-B was measured by radioimmunoassay every 12 hours for 14 days. Nineteen patients had anterior transmural myocardial infarcts AMI, 14 had inferior transmural myocardial infarcts (IMI) and 10 had subendocardial myocardial infarcts (SEMI). Infarct extension as detectd by a second rise in serum CK-B occurred in six patients (32%) with AMI, two (14%) with IMI and two (20%) with SEMI; these differences are not statistically significant. Infarct extension for all patients combined was 23%. Four patients with AMI also had infarct extension as determined by recurrent chest pain. ECG alterations and other enzyme changes. In the other six, the infarct extension was undetected clinically. Four patients with AMI and infarct extension died within 3 weeks after hospitalization. We did not note any additional morbidity or mortality in patients with infarct extension who had IMI or SEMI. There was no significant difference in the frequency of previous myocardial infarction, history of hypertension, diabetes mellitus or smoking history in patients with and without infarct extension shown by serum CK-B isoenzyme elevations. The measurement of serum CK-B values with a quantitative and sensitive assay suggests that myocardial infarct extension occurs more commonly than clinically recognized, but the frequency of extension may be less than that reported in patients in whom precordial mapping and total serum CK values were measured to identify this phenomenon.

Angina pectoris is a subjective symptom recognized primarily by a careful history. It must be differentiated from nonatherosclerotic chest pain. Arteriography should be performed when the diagnosis is in doubt or when the stable from becomes unstable. Management must include: attention to risk factors; awareness of precipitating factors; treatment of other illnesses such as hypertension and diabetes, and the use of drugs: nitroglycerin and, for long-term therapy, propranolol. If this regimen fails, patients should be considered for surgery.
