The relationships between aortic stenosis, coronary artery disease, angina pectoris, and myocardial infarction were examined in 173 patients with isolated calcific aortic stenosis who had coronary arteriography as well as cardiac catheterization. All were over age 40 and had definite cardiac symptoms; 156 later had aortic valve replacement. Coronary lesions narrowing the lumen by 50% or more were present in 37% of patients aged 40 to 59 and 68% of those aged 60 to 82. Coronary disease was present in 64% of patients with angina pectoris and 33% of those without angina. Angina which occurred only in association with dyspnea on exertion was associated with coronary disease in 45% of instances, whereas angina which also occurred on exertion without any dyspnea or which occurred with emotional stress, after meals, during sleep, or at rest unprovoked was associated with coronary disease in 80% of instances. Patients with coronary disease without any chest pain or with atypical pain considered nonanginal were men, usually over age 60, with congestive heart failure as the predominant symptom. Electrocardiograms showing transmural inferior or anterolateral infarction nearly always indicated coronary disease, while QS patterns in Leads V1-2 occurred frequently with normal coronary arteries. Serum cholesterol was elevated in 23% of those with coronary disease and 8% of those without. A group of patients with moderate aortic stenosis could be identified, with aortic valve areas of 0.55 to 0.80 cm. per square meter, in whom coronary disease was the sole or chief cause of symptoms. The operative mortality rate with aortic valve replacement was 9.6% in those with coronary disease and 1.4% in those without significant coronary disease. Coronary disease is frequently present in patients with calcific aortic stenosis, particularly in those over 60, those with angina, and those with symptoms despite only moderate aortic stenosis. The type of anginal syndrome, the ECG evidence of transmural infarction, and the coronary risk factors provide additional clues for clinical diagnosis.

Prior to major vascular surgery, hemodynamic studies were carried out in 63 patients by means of a flow-directed pulmonary artery balloon catheter. The results were correlated to electrocardiographic and roentgenologic findings, as well as to pertinent clinical information. Of 15 patients with either atrial fibrillation or both left ventricular hypertrophy and an increased cardiace volume, six had pulmonary pressures elevated above normal values; none of 14 patients with only one of the two signs (left ventricular hypertrophy or increased cardiac volume) had elevated pulmonary pressures. Also, the 34 patients with normal roentgenologic and electrocardiographic findings had normal hemodynamics, irrespective of a history of previous AMI, present angina or dyspnea on exertion. It is concluded that hemodynamic studies by means of a balloon-tipped catheter floating in the pulmonary artery are indicated before major surgery in patients with either atrial fibrillation or both electrocardiographic and roentgenologic signs of left ventricular hypertrophy. In such patients pulmonary pressures should be monitored during and after surgical operation.

Angina and increasing exertional dyspnea developed in a 53-year-old man 9 years after cardiac transplantation. Left heart catheterization revealed severe proximal triple coronary artery disease, and he underwent surgical revascularization. Now 18 months after the operation he continues to be free of symptoms.

We present 3 cases of apical hypertrophic cardiomyopathy. The presenting symptoms were dyspnea on exertion in 2 of 3 patients, typical anginal pain in 1 patient, atypical chest pain in 1 patient, and fatigue in 1 patient. One patient was asymptomatic with an abnormal electrocardiogram. Sustained apical impulse was noted in all patients, Grade 1/6 systolic murmur was audible in 2 patients. Electrocardiogram showed T wave inversion in the left precordial leads in all patients with amplitudes of 1.4, 0.8 and 2.0 mV, respectively. Isolated apical hypertrophy was noted in all patients. Two-dimensional echocardiogram and the left ventriculogram revealed a "spade-shaped" configuration of the left ventricular cavity at endo-diastole in only one patient. Left ventricular end diastolic pressures were elevated and coronary angiograms were normal in all 3 cases. We conclude that this disease entity should be considered in patients whose electrocardiogram shows a large inverted T wave in the left precordial leads, either accompanied by symptoms such as dyspnea on exertion or chest pain, or even when asymptomatic. Echocardiogram is the most useful screening tool in the diagnosis of apical hypertrophic cardiomyopathy.

A population survey was conducted in 1982-1983 among 3,812 persons aged 65 years and older residing in East Boston, Massachusetts, a geographically defined urban community. Three measurements of peak expiratory flow rate were obtained by using calibrated mini-Wright meters. Peak expiratory flow rate was strongly related to age, sex, smoking, and years smoked. After adjustment for these factors, low peak expiratory flow rate was associated with chronic respiratory symptoms (cough, wheeze, shortness of breath, exertional dyspnea, orthopnea, and paroxysmal nocturnal dyspnea; p less than 0.0001) and with certain cardiovascular variables (history of stroke, p = 0.0014; angina, p = 0.05; and high pulse rate, p = 0.004). No significant associations were found with history of myocardial infarction or systolic and diastolic blood pressures. Peak expiratory flow rate was positively related to education (p less than 0.0001) and income (p less than 0.0001). Peak expiratory flow rate also was strongly related (p less than 0.0001) to measures of functional ability and physical activity, self-assessment of health, and simple measures of cognitive function. The correlations of peak expiratory flow rate with pulmonary symptoms and other indices of chronic disease raise the possibility that peak expiratory flow rate will predict mortality in an elderly population.

Balloon valvuloplasty has been shown to be an effective treatment for adults with aortic stenosis, typically providing a 50 to 80% increase in aortic valve area and marked improvement in exertional dyspnea, angina and syncope. However, the duration of this hemodynamic and clinical improvement is uncertain. Forty-two patients were followed for 10.2 +/- 0.5 months. Balloon valvuloplasty caused dramatic immediate reduction in the number of patients with moderate or severe dyspnea (80 to 14%), moderate or severe angina (39 to 2%) and syncope (30 to 2%). Furthermore, this improvement in symptoms continued for the duration of the follow-up period in most patients. Echocardiographic aortic valve mean gradient and area determined at 3-month intervals, however, showed a trend toward or return to prevalvuloplasty levels by 9 months' follow-up in 13 of 25 patients (52%), whereas 12 of 25 patients showed no deterioration in their hemodynamic parameters. This trend toward restenosis was accompanied by symptomatic deterioration in 5 of 13 patients (38%). This tendency toward restenosis in greater than 50% of patients by 9 months underscores the need for further technical improvements if balloon valvuloplasty is to be widely applied. Even with these limitations, however, balloon valvuloplasty seems to provide a significant improvement in actuarial survival compared with the natural history of elderly patients with severe aortic stenosis.

Two patients are described, each with a large left ventricular aneurysm and severe coronary artery disease, and each with an ejection fraction lower than 30% and in congestive heart failure. In both, the left latissimus dorsi (LD) muscle was used in the repair of the ventricular aneurysm because preoperative studies demonstrated that there was concomitant coronary artery disease, and there was a strong suggestion that resection of the entire aneurysm would seriously compromise the residual ventricular capacity. One patient had an 18-year history of coronary occlusion with two infarctions. A large, calcified ventricular aneurysm developed, and despite vigorous medical treatment, intractable congestive heart failure and angina persisted. The diffuse coronary artery disease made this patient a poor candidate for bypass grafting. The other patient sustained an acute myocardial infarction 5 months prior to operation. The left anterior descending coronary artery was totally occluded, and a large apical aneurysm developed along with an akinetic anterior wall and septum. After his heart attack, the patient had progressive dyspnea on exertion. Following operation in both patients, the transpositioned LD, then a component in the repair of the left ventricular wall, was electrically trained to synchronously contract with each systole, driven by a standard dual-chamber cardiac pacemaker. Steady improvement and a return to normal activities were observed in both patients. There was an indication of improved ejection fraction with synchronous contraction of the skeletal muscle.

In patients with hypertrophic cardiomyopathy, clinical symptoms such as exertional dyspnea, angina and collapse are considered to be rather the consequence of diastolic than of systolic dysfunction of the left ventricle. Beta-blocker therapy is aimed at reducing systolic overcontraction while calcium blockers predominantly therapy is aimed at reducing systolic overcontraction while calcium blockers predominantly improve diastolic filling characteristics. Therefore 61 consecutive patients with well defined hypertrophic cardiomyopathy were treated with calcium channel blockers: 60 patients with verapamil at average dose 530 mg (320 to 720 mg/d) and one patient received 30 mg nifedipine. All patients had clinical, noninvasive and cardiac catheterization evaluation at the time of entry into the study. Therapy was continued for an average of 54 months (10 to 96). Follow-up studies were performed at 6-month intervals. Subjective improvement was achieved in 47 of 55 symptomatic patients (85%). Heart size, judged as heart volume from tele-chest X-ray in supine position, showed a reduction in 36/61, no change in 15/61 and increase in 10/61. On average in all 61 patients, a significant reduction from 947 to 833 ml/1.73 m2 was seen. Twenty-six patients who had been followed for an average of 24 months prior to verapamil therapy on beta blockers or no treatment had heart volume increases averaging 12% in the pre-verapamil period. Electrocardiography (ECG) showed a significant reduction in QRS amplitude and a tendency towards normalization of ST/T segments. Serial echocardiography study showed small but significant reduction in left atrial diameter. Repeat catheterization was performed in 19 patients and a significant reduction in intraventricular pressure gradient, left ventricular muscle mass and coronary artery diameter was demonstrated. Three patients died during the study (256 patient-treatment-years) for an annual mortality rate of 1.3%. This mortality is considerably lower than reported for patients receiving no treatment, beta-blockade, or surgery. Of all 61 patients only one had surgery related to the hypertrophic cardiomyopathy. One patient had the dose of verapamil reduced because of the occurrence of heart block. No patient discontinued the drug because of side-effects. Utilizing serial noninvasive and invasive studies, we conclude that verapamil therapy in hypertrophic cardiomyopathy results in objective and subjective improvement, a low death rate and little need for operation as compared to standard therapy.

Twelve hundred twenty-six (1,226) persons representative of the noninstitutionalized United States population aged 65-74 years were interviewed and examined as part of the 1971-1975 Health and Nutrition Examination Survey (HANES). Using information available in the HANES data base, standards for what could be considered minimally acceptable care were developed for five tracer conditions. Rates of "deficient" care were: angina, 46 percent; dyspnea on exertion, 78 per cent; hypertension, 26 per cent; hearing impairment, 61 per cent; depression, 80 per cent. Deficient care was analyzed by gender, race, income, locale, and self-rated health status. Only low income emerged as a consistent risk factor for deficient care, with the relative odds for deficient care for poor patients as compared with non-poor patients ranging from 2.7 to 5.6 (P less than 0.05) for four of five conditions. A subgroup analysis attempted to determine whether deficiencies were caused by limited access to physicians, underreporting of symptoms, or barriers that occurred after presenting complaints to a physician. The analysis revealed that for three of four symptomatic conditions, the poor and non-poor patients were equally likely to report their symptoms, whereas the poor were more likely to receive "deficient" care after presenting complaints to physicians. The ramifications of these findings as they pertain to the present situation are discussed.

The effect of chewable isosorbide dinitrate on submaximal bicycle exercise capacity was evaluated in a double-blind randomized study involving 13 patients with chronic heart failure. All patients had impaired maximal exercise capacity (VO2 max = 12.0 +/- 2.6 ml/kg/min) due to fatigue and dyspnea but not angina. The administration of isosorbide dinitrate lowered the resting mean blood pressure (82 +/- 9. mm Hg to 78 +/- 10 mm Hg, (p less than 0.03)) and the resulting pulmonary wedge pressure (26 +/- 5 mm Hg to 12 +/- 6 mm Hg, (p less than 0.01)). Isosorbide dinitrate acutely improved exercise duration during upright bicycle exercise at a workload fixed at 50 percent of the maximal workload (placebo): 21.8 +/- 14.1 min vs isosorbide dinitrate: 31.4 +/- 13.6 min, (p less than 0.003)) due to reduced exertional dyspnea. Administration of chewable isosorbide dinitrate acutely improved submaximal exercise tolerance in patients with chronic heart failure.
