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.

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.

To elucidate the clinical characteristics of pulmonary edema in unstable angina, 120 patients with unstable angina who admitted to the hospital within 6 hours after the onset of chest pain were studied. The criteria for the diagnosis of pulmonary edema included interstitial pulmonary edema and diffuse alveolar edema. Pulmonary edema was present in 24 patients. In these patients, the duration of chest pain was relatively longer, and the incidences of diabetes mellitus, emergency coronary revascularization and multiple-vessel coronary artery disease were higher than in those without pulmonary edema. In addition, in-hospital mortality rate in patients with pulmonary edema was higher than in those without it (21 vs 1%, p < 0.001), which is probably due to a large area of myocardial ischemia. For these patients, therefore, early diagnosis and appropriate therapy to save viable segments of the myocardium are mandatory.

The existence of specific, age-related changes in gastrointestinal motility with clinical significance is controversial. Beside the more infrequent primary motility disorders, secondary motility disturbances associated with collagen vascular diseases, endocrinopathies, and neuromuscular diseases are prominent in the older and often multimorbid patients. Especially in geriatric patients, motility associated symptoms are undesired side-effects of drug therapy. The pathophysiology, clinical syndromes, and therapeutic principles of motility disorders in the elderly are discussed. The major symptoms of esophageal dysfunction are dysphagia, chest pain, heartburn, and regurgitation. Oropharyngeal dysphagia, mostly caused by cerebrovascular accidents and other neurologic disorders, leads to disturbances in food intake, and is often complicated by broncho-pulmonary infections arising from recurrent aspiration of food or saliva. Gastrointestinal reflux disease and spastic motility disorders of the esophagus are regarded as possible causes of angina-like chest pain after exclusion of cardiac diseases. Motility disturbances of the stomach and small bowel are often related to systemic disease (i.e., diabetes mellitus, chronic intestinal pseudo-obstruction) of drug side-effects. Mental and physical decline, reduced fluid intake, and constipating drugs are the most relevant factors for idiopathic constipation in the elderly. Fecal incontinence means a great psychological strain for older patients and leads to social isolation.

This study prospectively evaluates the long-term prognosis of patients admitted with chest pain under suspicion of acute myocardial infarction (AMI) with and without confirmed diagnosis. All patients below 76 years of age, free of other severe diseases and alive at discharge, who were admitted to a coronary care unit of a well-defined region during 1 year, constituted the study population. In all, 275 patients with and 257 patients without confirmed AMI (non-AMI) were included. During 7 years of follow-up, 122 cardiac events (96 cardiac deaths and 26 nonfatal AMI) occurred in the AMI patients, and 69 (44 cardiac deaths and 25 nonfatal AMI) were observed in the non-AMI patients. Using univariate analysis, the following risk variables were significantly related to an impaired prognosis of non-AMI patients: age, a history of previous AMI, angina pectoris, clinical heart failure, diabetes and ST or T changes in the electrocardiogram (ECG) on admission. By multivariate analysis, the following risk factors contained independent prognostic information for non-AMI patients: (1) a history of angina pectoris and (2) ST and T changes on the ECG on admission. We conclude that a subset of non-AMI patients at high risk for cardiac events even in the long term can be identified from the medical history and the ECG on admission. These patients should be carefully evaluated prior to discharge, whereas patients without signs of ischemic heart disease have an excellent prognosis.

The clinical features of congestive heart failure in the elderly were investigated in 104 patients (57 males, 47 females, mean age of 79.2). Patients were divided into two subgroups, the readmission group, 33 patients who were readmitted within 6 months after discharge, and the non-readmission group. Chief complaints were dyspnea, edema, chest pain, loss of appetite, chest compression, and palpitation. Heart failure was caused by infection, myocardial ischemia, arrhythmia, inappropriate drug usage including poor drug compliance, the use of beta-blockers, excessive intake of sodium, and anemia. Careful use of drug was essential especially in the readmission group. Major underlying heart disease were ischemic heart disease (39.4%), valvular disease (26.9%), hypertensive heart disease (9.6%), with cardiomyopathy, congenital heart disease seen in the minority. There was no statistically significant difference in underlying heart diseases between the two groups. Supraventricular arrhythmias such as atrial fibrillations, paroxysmal atrial fibrillations, paroxysmal supraventricular tachycardias, and premature atrial contractions were noted in 85.3% of the cases. Drugs for treatment were diuretics, digitalis, isosorbide dinitrate, calcium antagonists. ACE inhibitors and alpha-blockers were also used, showing that vasodilators were more extensively used than before. The major complications were hypertension (39.4%), renal dysfunction (27.9%), cerebrovascular disease (26.9%), diabetes mellitus (16.5%), arteriosclerosis obliterans (7.7%). Renal dysfunction, arteriosclerosis obliterans was seen significantly more frequently in the readmission group. The prognosis at one year after admission was significantly worse in the readmission group. In summary, the major underlying diseases were ischemic heart disease, valvular disease, and hypertensive heart disease. Ischemic heart disease was seen more frequently than in previous investigations at our hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute myocardial infarction in pregnancy is a rare event that carries substantial morbidity and mortality. New technologies have been developed in cardiology to open obstructed vessels during the acute evolution of coronary thrombosis. We present a case of acute postpartum myocardial infarction in a woman with class F/R diabetes. She underwent successful balloon angioplasty but developed chest pain suspicious of angina pectoris 6 weeks after the procedure. A thallium scan demonstrated fixed defects in the inferoposterior and posterolateral segments and minimal apical redistribution. This represents the second case of angioplasty performed in pregnancy and the first for an acute myocardial infarction.

A number of practical office and bedside clues to cardiac disease in infants and children have been passed on through the years. They relate to the history, to the inspection and palpation components of the physical examination, and to knowledge of the specific cardiac defects that are likely to be associated with certain clinical syndromes. With the possible exception of coarctation of the aorta, the clues are not diagnostically specific. In many instances, however, they serve to narrow a broad array of diagnostic possibilities to 2 or 3 and, with the aid of other clues and auscultation, they can often be distinguished from one another. When a primary care physician is confronted with a child who has an incidental murmur that is "probably" innocent but could be organic, useful clues favoring an organic murmur are a history of congenital heart disease in a first-degree relative; a history of maternal rubella syndrome, alcohol use, or teratogenic drug use during pregnancy; a history of inappropriate sweating; a history of syncope, chest pain, or squatting; maternal diabetes mellitus; premature birth; birth at a high altitude; cyanosis; abnormal pulsations; recurrent bronchiolitis or pneumonia; chronic unexplained hoarseness; asymmetric facies with crying; and a physical appearance suggestive of a clinical syndrome.
