Myocardial infarct in a 37-year-old woman treated with oral contraceptives (.1 mg mestranol and 1 mg ethynodiol diacetate) for 6 years is reported. The patient had received chest bruises in an auto accident 10 weeks before the infarct, but had experienced no pain at the time and had required no medical treatment. She noted chest pain, which disappeared after a short time, some 8 weeks after the accident. 10 weeks after the accident, she presented with typical signs of myocardial infarct; treatment included digitalis, diuretics, and a anticoagulants. Except for slight overweight and smoking (15 cigarettes daily) the patient had no heart risk factors. Coronary angiography revealed isolated subtotal stenosis of the left anterior descending artery. The etiology of the infarct is discussed.

Short-term results of aggressive surgical management were compared with results of medical management in forty-three patients with preinfarction angina admitted to the coronary-care unit (CCU) over an 18 month period. These patients were selected from 1,609 consecutive admissions to the CCU because they met strict criteria for preinfarction angina: severe chest pain at rest, ST-segment elevation or depression during pain which subsided rapidly after cessation of pain, and normal serum enzymes (CPK, SGOT, and LDH). Twenty-three patients had coronary angiography, done with operating room and pump standby. One patient, who had total occlusion of the left main coronary artery, died during the study. Twenty-one of the remaining patients were considered surgical candidates, and were treated immediately after angiography with 1 to 3 vein bypass grafts. There was one late postoperative death and, of the 20 survivors, 2 had ECG evidence of acute myocardial infarction and one had mild angina at time of discharge. In contrast, of the 21 patients treated medically, 13 sustained acute MI, resulting in 8 instances of congestive heart failure and 4 cases of ventricular fibrillation. Four patients died in cardiogenic shock. With the use of rigid criteria, a small subgroup of patients with variant angina at high risk of developing AMI has been identified and categorized as having preinfarction angina. Our experience suggests that aggressive surgery immediately following coronary angiography offers a lower incidence of MI, morbidity, and death than does medical management.

We report the clinical features and the results of investigation and surgery in 20 patients with significant left main coronary artery stenosis. All had moderate to severe angina; 8 had pain at rest. Three had dyspnoea as a major symptom. The electrocardiogram was abnormal in 17, with evidence of previous myocardial infarction in 10. Of the 11 patients exercised, 8 developed chest pain. Nine patients had a normal left ventriculogram. At coronary angiography all patients had major disease elsewhere in addition to the left main coronary artery stenosis. There were no deaths or major complications associated with this investigation. One patient was unsuitable for surgery because of diffuse left ventricular hypokinesia, one had a fatal myocardial infarction while awaiting operation, and there was one preoperative death. Sixteen of the 17 surgical survivors are free from angina. There has been a significant improvement in the maximum exercise capacity in the 10 patients who had pre- and postoperative exercise tests.

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.

Ambulatory electrocardiographic monitoring was employed in 33 patients with angina pectoris and abnormal stress tests to determine the frequency with which myocardial ischemia manifested by painless ST-segment depression occurred during normal activity. ST-segment depression occurred in 24 patients during the monitoring period; and in 21, it occurred either solely in the absence of pain or both with and without pain. Of 109 recorded episodes of ST-segment depression, 61 percent were painless. The frequency of painless ST-segment depression was independent of activity other than automobile driving, during which all episodes were painless. In patients who smoked cigarettes, ST-segment depression was more common while smoking, but the incidence of painless ST-segment depression was not altered. The study indicates that ST-segment depression occurs more commonly in the absence than in the presence of chest pain and that ambulatory electrocardiographic monitoring is a useful method of determining the frequency of myocardial ischemia during normal daily activity.

Malignant pleural mesothelioma may be composed of sarcomatous, epitheliomatous or mixed cell types. They can be differentiated from localized, benign mesothelioma. Malignant pleural mesothelioma is a rapidly fatal tumor that poses serious diagnostic and therapeutic problems. A series of 19 cases was compiled at the North Carolina Baptist Hospital, and data from these cases were compared to those of other series. The average survival time was 10 months. The most common symptoms were dyspnea, chest pain, pleural effusion, and weight loss. Three patients had a definite history of exposure to asbestos; in 6 more there was a questionable exposure. The most helpful investigative screening tool was the chest roentgenogram, in that it demonstrated an intrathoracic abnormality; however, mesothelioma could not be differentiated from inflammatory reaction or bronchogenic carcinoma with pleural effusion. Sputum cytology as well as pleural effusion cytology was only suggestive of malignancy. Bronchoscopy was not helpful. Needle biopsy yielded malignant cells in 3 of 8 patients. Exploratory thoracotomy was the most accurate means of diagnosis but was frequently followed by seeding into the incision and severe, intractable incisional pain. Therapy proved to be palliative at best. Thoracotomy did not alter the course of the disease; in fact, the production of severe incisional pain was deleterious to the patient's well-being. Cordotomy done in 3 patients brought no relief. Neither radiation therapy nor chemotherapy had a significant effect on survival time or palliation.

The primary purpose of this report is to extend the range of the Multidimensional Pain Inventory (MPI) to include patients with nonorganic chest pain. Previous research with the MPI has not included this patient population, although this instrument has been used to derive an empirically based taxonomy of patient responses to chronic pain. Scale scores are provided for a sample of 43 chest pain patients and compared with normative scores from samples of chronic lower back pain patients and patients suffering from temporomandibular disorder. The MPI taxonomy was applicable for only 34.8% (N = 15) of this sample. Scale intercorrelations are examined and compared with those derived during development of the MPI, to explore reasons for this low classification rate. The results are discussed in light of cognitive-behavioral factors present in persistent chest pain, with implications for scale development and use of the MPI.

A 16 year old teenager with chest pain came to the emergency room at Children's Hospital in Charleston, South Carolina. Her sharp, constant midsternal pain and breathing difficulties began the morning of admission. 1 week before admission, she experienced a similar but less intense pain which resolved spontaneously. She was taking low-dose, triphasic oral contraceptives (OCs) as treatment for severe dysmenorrhea and dysfunctional uterine bleeding. She had no family history of elevated lipids, blood or clotting disorders, and cardiovascular disease. She did not smoke. She was obese (137.3 kg). She had elevated blood pressure (147/33 mm Hg), a high low-density lipoprotein count (140 mg/dL), and a high total cholesterol count (237 mg/dL). Her tender right calf was larger than the left calf. She had decreased perfusion of the entire left lung and right lower lobe. A pulmonary angiogram revealed emboli, and ultrasound of the legs revealed a thrombus behind the right knee. The physicians discontinued the OCs. They administered 2 anticoagulants--intravenous heparin followed by oral sodium warfarin for 6 months. Her respiratory distress ended within several days. Her right calf was no longer tender after 1 week. The physicians discharged her on a low-cholesterol, low-fat diet. They suggested she reduce her weight and exercise more often. She did not experience another venous thrombosis or pulmonary embolus. It appeared that the OCs contributed to her thromboembolism; yet, she did lead a sedentary lifestyle and was considerably overweight. Even though thromboembolism is rare in adolescents with no underlying predisposition for cardiovascular disease and who do not smoke, physicians should watch for sizeable changes in blood pressure, lipids, and cholesterol level as well as symptoms of deep venous thrombosis and cardiovascular disease.

Study objectives were to characterize the clinical syndrome of chronic idiopathic esophageal ulceration in patients with acquired immunodeficiency syndrome (AIDS), to determine the extent of local human immunodeficiency virus (HIV) infection, and to evaluate the effect of corticosteroid therapy upon symptoms and healing. Twelve AIDS patients with chronic esophageal ulcers whose etiology remained unknown after clinical evaluation were the subjects. All patients complained of severe odynophagia, chest pain, and weight loss. Barium radiography and endoscopy demonstrated large, undermined ulcers with severe acute inflammation. No evidence of herpes simplex viruses I or II, cytomegalovirus, fungi, or tumors were found histologically. Evidence of HIV was found in all ulcers using a combination of RNA in situ hybridization, immunohistochemistry, and quantitative antigen capture enzyme-linked immunosorbent assay of tissue homogenates. Steroid therapy by the oral or intravenous routes or by direct intralesional injection resulted in pain relief, weight gain in 10 patients, and ulcer healing in five patients. A characteristic clinical syndrome of chronic idiopathic esophageal ulceration may occur in patients with AIDS, related to local HIV infection in the esophagus. Corticosteroids relieve symptoms and may promote healing of the ulcer.

Recently, 24-h recording of intraesophageal pH and pressure signals in ambulatory subjects has become possible. Several research applications of the technique have emerged, but until now only a few clinical applications have been established, the most important of which is noncardiac chest pain. In the computer analysis of the signals, the patient with noncardiac chest pain is used as his or her own control; motility and pH profiles during pain are compared with asymptomatic base-line values obtained from the same patient. Automated analysis by means of a computer avoids observer bias and saves time. By means of 24-h monitoring, motor abnormalities have been identified as the cause of the chest pain in 4.5% to 18% and reflux in 4.5% to 25% of the patients studied. In addition, patients were identified who have both dysmotility- and reflux-related pain episodes. The yield of 24-h monitoring is highest in patients who have frequent pain episodes. A high yield of 24-h monitoring was found in patients with noncardiac chest pain admitted to a coronary care unit. Seventy-six per cent of these patients were found to have either reflux- of dysmotility-related chest pain. Patients with proven coronary artery disease who do not respond well to adequate treatment frequently have gastroesophageal reflux (39%) or esophageal motor abnormalities (50%) as the cause of their ongoing pain attacks. In these patients, identification of the esophageal cause of the symptoms not only helps the physician to select the optimal treatment but also reduces the patient's need for medical care.
