Spasm of coronary arteries can cause chest pain indistinguishable from classic angina pectoris in patients without atherosclerosis of these vessels or recognizable heart disease. Associated electrocardiographic changes usually correspond to the coronary artery affected and disappear when the attack of pain ends. Sublingual nitrates are excellent agents for the control of the episodic anginal symptoms. There have been scattered reports of myocardial infarction occurring in patients with normal coronary arteries; a role of arterial spasm in these cases in speculative.

A study of 55 patients with heart disease suspected of being viral in origin was carried out a Medical College Hospital, Nagpur, over a period of 2 years. Virus studies as well as other routine tests were carried out on all patients. In 19 patients a virus aetiology of the heart disease was proved by isolation of one of the subtypes of Coxsackie B virus and/or on the basis of fourfold rise in neutralizing antibody titre in paired sera. Of these patients, 5 had acute myocarditis and 5 had acute myopericarditis; 3 had acute pericarditis; 3 had congestive cardiac failure of obscure aetiology; 2 had pleuropericarditis, and the remaining 1 developed post-partum heart failure with cardiogenic shock. All had electrocardiographic abnormalities. Thirteen had cardiomegaly; 1 had a right-sided pleural effusion and 2 had pericardial effusion. Virus could not be isolated from pericardial fluid or pleural fluid in these 3 patients. Follow-up studies up to 10 weeks from discharge revealed that 8 patients were clinically normal but 4 of these 8 had persisting ST-T wave changes, and in 4 the electrocardiogram had returned to normal. Of the remaining 11 patients, 3 had persistent chronic heart failure, 3 had vague symptoms of praecordial pain but no abnormal signs, and 5 patients were lost to follow-up.

Bicycle ergometry on the "Elema" electrical bicycle ergometer was conducted on 6, patients of climacteric age (41 to 55 years) with pain in the region of the heart and ECG changes. The method made it possible to confirm the diagnosis of climacteric cardiopathy in 39 and to reveal climacteric cardiopathy and concurrent ischemic heart disease in 23 patients. It was noted that physical load had a favourable effect on processes of repolarization in the myocardium of patients with climacteric cardiopathy.

Treadmill stress testing is used in assessing the condition of patients with known or suspected heart disease. We did a prospective study to clarify physician ordering and integration of the test. Ordering criteria were always complied with, although most tests were ordered for evaluation of atypical chest pain and only a few for high risk patients with known cardiac dysfunction, indicating a misplaced emphasis on the diagnostic capabilities of the test. Tests in patients with atypical chest pain and stress-induced ischemic changes were always integrated, but in 30 percent of patients with atypical pain and no stress-induced electrocardiographic changes, the tests were not used in patient management. This was often due to the misconception that negative findings on a stress test excluded coronary disease. Physicians should be alerted to this misplaced emphasis and misconception.

We report 11 cases of bacterial endocarditis with muscular and articular manifestations seen over the past ten years. There was arthralgia in 7 cases, vertebral pain in 7 cases and myalgia in 3 cases. Arthritis consisted of a monoarthritis of the ankle in 2 cases and oligoarthritis in 2 cases. There were also 2 cases of lumbar spondylodiscitis and 1 of finger clubbing in the series. The underlying heart disease was a valvular lesion of the left side of the heart in 10 cases out of 11 and the organism isolated by blood culture was a streptococcus in 9 cases and a staphylococcus in 11. We emphasis the need for early diagnosis and appropriate antibiotic therapy, in the absence of which the course may be fatal in the short term, as it was the case in one of our own patients.

We compared 41 patients with angiographic proof of pulmonary embolism and clinical signs of pulmonary infarction (as evidenced by an infiltrate on x-ray study and pleuritic pain in the area of the embolus) with 24 patients with pulmonary embolism but without infarction. Only 18 of the 41 patients with pulmonary infarction had associated heart disease. Pulmonary infarction was uncommon when emboli obstructed central arteries but frequent when distal arteries were occluded. Follow-up x-ray examination showed that the infiltrates resolved in the patients with pulmonary infarction without heart disease, but persisted when heart disease was present. We suggest that obstruction of distal arteries results in pulmonary hemorrhage owing to an influx of bronchial arterial blood at systemic pressure. Hemorrhage causes symptoms and x-ray changes usually attributed to pulmonary infarction. However, hemorrhage resolves without infarction in patients without, but progresses to infarction in those with, heart disease.

The parturient with a cardiac valve prosthesis presents a twofold problem of management: (1) that of a rising cardiac workload in the presence of serious heart disease, and (2) that of chronic anticoagulant therapy. Pain relief, a shortened 2nd stage of labor, and avoidance of bearing-down efforts reduce stress. Vaginal delivery is preferred to cesarean section, and segmental lumbar extradural block is the optimal anesthetic method. Oxytocics must be used with caution and heparin is preferred to longacting oral anticoagulants.

A search was made for predictors of sudden cardiac death (SCD) among 197 men, age 40 to 79, who had multiphasic health checkups and experienced SCD 2 days to 5 1/2 years later (mean 18.1 months). Two age-sex-race-matched control groups, one matched and one unmatched for standard coronary risk factors, have been compared to the cases. In this ambulatory population, SCD occurred largely in persons with prior diagnosed heart disease. Standard coronary risk factors were confirmed as predictors of SCD. Predictors among other laboratory and quantitative tests include chylous serum, uric acid, hemoglobin, leukocyte count, pulse rate, diminished lung volumes, and hearing loss. Some of these had predictive value independent of standard risk factors. Pain tolerance was not related to SCD or to death in, versus out of hospital. Most of these predictors were not related to terminal symptom duration; this suggests a relationship more to the underlying atherosclerotic process than to the terminal fatal mechanism.

Over the span of two or three days in August, 1972, in two separate communities in eastern Massachusetts two men, one aged 39, the other 66, each without previous overt heart disease, were stung by wasps. Each went into shock rapidly after an interval of over a half-hour developed chest pain and, later, sequential electrocardiographic changes diagnostic of acute myocardial infarction. Each survived; each had normal electrocardiograms before the sting. Though preexistent coronary artery disease can be excluded in neither, the view is favored that acute myocardial infarction in each was caused by deficient coronary perfusion secondary to anaphylactic shock induced by the wasp stings. An intriguing case was just recently reported58 of a 62-year-old man with previous angina who developed pulmonary edema but no chest pain following wasp sting and went on to show rapidly reversed electrocardiographic changes attributable to subendocardial ischemia or infarction. In a sense, this sequence fills the gap as an intermediate phase between the normal and the two individuals described here who developed pain after anaphylactic shock, then proceeded, perhaps through this phase, to develop transmural infarction.

200 cases with the Qi Stagnation and Blood Stasis type of coronary heart disease were divided into two groups randomly. Group A used Rose Shu-Xin (heart comforting) oral liquid which is mainly made from the local natural resources-Rose compound products. While group B used Salvia miltiorrhiza (co.) tablet. The results showed that in group A, the total effective rate was 98% and the ECG improving rate was 75%, while in group B, it was 50% and 40% respectively. There was significant difference between group A and B (P < 0.01). Experiments have proved that the Rose oral liquid could improve the myocardial ischemia of the experimental rabbit. It could also reduce the size of infarction area, thus protected the heart from infarction. No adverse action was found in animal experiments and clinical practice. It has proved that the oral liquid could dredge the Liver and regulate the flow of Qi, and remove any obstruction to it. It could also promote the circulation of Blood and relieve pain. It gave the Heart disease a cure from the Liver in TCM theory.
