There is a clinical dilemma in the treatment of patients with hypothyroidism and coronary artery disease; excess thyroid hormone administration may exacerbate anginal symptoms, and yet inadequate thyroid replacement may induce congestive heart failure. A case of successful coronary artery bypass grafting in a patient with angina pectoris and hypothyroidism is described in this paper. A 55 year-old woman with this complication initially received thyroid replacement therapy under strict monitoring. Forty days after the start of the thyroid replacement therapy, serum levels of thyroid hormone had reached the normal range, and then coronary artery bypass grafting was successfully performed. She recovered without any complications, and is now free from chest pain in spite of thyroid replacement therapy. 相似文献

Variant angina pectoris caused by coronary artery spasm 总被引:1,自引:0,他引:1
A 58 year old man presented with Prinzmetal's variant angina. Recurrent ventricular tachyarrhythmias, uncontrolled by various medical regimens, prompted cardiac catheterization. At catheterization a congenital anomaly of the coronary circulation was demonstrated, consisting of a single coronary artery. During coronary angiography, arterial spasm occurred associated with chest pain and ventricular ectopic beats. This was relieved by the acute administration of sublingual nitrates. Subsequently, despite the frequent administration of nitroglycerin and isosorbide dinitrate, chest pain and ventricular tachycardia continued to occur sporadically. Because of this, saphenous vein bypass surgery was performed. After an initial symptom-free interval, the chest pain recurred. Recatheterization revealed complete occlusion of the distal circumflex artery at the insertion of the implanted saphenous vein. The use of aortocoronary saphenous vein bypass grafting for relief of symptomatic coronary arterial spasm is questioned. 相似文献

Breathlessness, angina pectoris and coronary artery disease 总被引:1,自引:0,他引:1
The relation of breathlessness to angina was examined in 7,735 middle-aged British men. Among men who did not report breathlessness, the age-standardized prevalence rate of angina was 4%. In men with mild, moderate or severe breathlessness, the prevalence rates of angina were 16, 29 and 41%, respectively. The association between breathlessness and angina was independent of age or cigarette smoking, with similar relations observed in men who had never smoked. The prevalence of electrocardiograms revealing ischemia increased with the severity of breathlessness, even in men without angina or other evidence of coronary artery disease (CAD) at screening. In men with a low forced expiratory volume in 1 second, the prevalence of angina was also increased, but the association was much weaker than that observed between angina and breathlessness. After a 5-year follow-up, 25% of men severely breathless at screening but without any initial evidence of CAD had developed angina, 5% had had a heart attack (half of these were fatal) and 7% were dead from causes other than CAD. The corresponding rates for men not breathless at screening and without evidence of CAD were: 4% angina, 2.5% heart attack and 2% dead from causes other than CAD. Breathlessness appears to be an early indicator of CAD in the absence of either angina or electrocardiographic evidence of ischemia. 相似文献

Essential thrombocythemia associated with angina pectoris with unusual coronary artery findings 总被引:1,自引:0,他引:1
A case of ET associated with angina pectoris is presented. Angiography showed a 3.0-cm long mosaic-like thrombus shadow consisting of small filling defects in the proximal left anterior descending artery. The lesion could not be reduced with warfarin, ticlopidine, trapidil, urokinase or melphalan. Coronary artery bypass grafting was performed successfully. 相似文献

The data from 88 patients (pts) with aortic stenosis (AS) were reviewed to determine relationships between angina pectoris (AP) and coronary artery disease (CAD). Results of surgery performed in 81 of these pts was analyzed. All pts had coronary arterlograms, and lesions ≥ 50% were considered significant. Fifty-nine pts had an aortic valve gradient measured at catheterization ≥ 40 mmHg, and in 29 pts, AS was confirmed at operation. Sixty-eight pts (77%) experienced AP, and 32 had coexisting CAD (47%); 9 of 20 pts without AP had CAD (45%). There were no significant differences in the incidence of AP in pts divided into subgroups by the aortic valve gradient (40–50, 51–100, 101–200 mmHg) or age (40–59, 60–81 years. Also, no significant differences were found in the incidence or extent of CAD between the two age groups; the extent of CAD was similar regardless of the presence or absence of AP. In pts with AP (1) CAD was more likely in pts ≥ 60 years of age; (2) CAD was less likely when the aortic valve gradient was > 100 mmHg, suggesting that AP in these pts was due to hemodynamically severe AS. All pts with 3-vessel CAD experienced AP, and the aortic valve gradient was less in these pts than in those with no CAD or less extensive CAD. In 19 pts with combined AS and CAD who had both the aortic valve replaced and a revascularization operation only 1 of pts died in the hospital, while 3 of 19 pts with combined AS and CAD who had aortic valve replacement alone died. In this study a significant number of pts with AS experienced AP, and the presence or absence of AP did not predict coexisting CAD. Coronary arteriography is recommended in the evaluation of pts ≥ 40 years of age with AS. The operative mortality appears to be decreased in pts with AS and CAD who have combined surgery. 相似文献

A patient had total occlusion of the left main coronary artery that was proved by coronary arteriography. The patient was initially seen with clinical signs of congestive heart failure but without symptoms of angina pectoris or ECG evidence of myocardial infarction. The patient's extensive right-to-left coronary artery collaterals may have contributed to the absence of chest pain. Because of the severe left ventricular dysfunction and the absence of chest pain, the patient was treated with medical therapy. Six months after the cardiac catheterization, he was alive and well under New York Heart Association functional classification II. 相似文献

One hundred eight consecutive patients with proved coronary artery disease and reproducible exercise-induced myocardial ischemia were studied. During repeated exercise testing, 52 patients (Group I) had myocardial ischemia in the absence of pain (silent ischemia) whereas 56 patients (Group II) experienced anginal symptoms in the presence of electrocardiographic signs of ischemia. A pulpal test was carried out in all patients using an electrical dental stimulator commonly used in dentistry. Electrical current was delivered in increasing intensity from 10 to 500 mA, and the dental pain threshold and the reaction of the patients to maximal stimulation were determined. During the pulpal test, 71.2% of the patients in Group I did not experience pain, even at maximal stimulation (threshold 0), 11.5% were sensitive at threshold I (10 to 200 mA) and 17.3% felt pain at threshold II (210 to 500 mA). In Group II, 69.7% of the patients complained of dental pain at the low intensity test current (threshold I), 10.7% at threshold II and 19.6% at threshold 0. In Group I, 71.2% of patients did not have discomfort (reaction -), even at maximal stimulation, 21.1% had a mild reaction (reaction +) and 7.7% had an intense painful reaction (reaction ++). In Group II, 80.4% of patients were sensitive to the pulpar test (67.9% reported intense painful sensation at maximal stimulation, 12.5% had a mild reaction); 19.6% of patients had no reaction. The two groups of patients were similar with respect to age, sex and angiographic features.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

We describe a 55-year-old female patient with multiple plexiform coronary artery-pulmonary artery fistulas, who presented with ischemic episodes accompanying an inversion of T wave on an electrocardiogram even though it was a small shunt size. The surgical procedure involved closure of the openings of the fistulas from inside the pulmonary trunk using cardiopulmonary bypass with additional ligations. Postoperative coronary angiogram revealed complete interruption of the coronary artery-pulmonary trunk fistulas resulting in complete resolution of the patient's chest symptoms. 相似文献

The distribution and severity of coronary disease in 500 patients with angina pectoris and at least one area of 50% or greater reduction of luminal diameter in a major coronary artery were compared with respect to patients' age and coronary arterial pattern. The coronary arterial patterns were separated into right (360 patients), mixed (89 patients), and left (51 patients) systems, depending upon the blood supply to the inferior surface of the left ventricle. The following relationships were noted: 1) In patients with angina pectoris, the distribution and severity of coronary artery disease is similar from the third to eighth decade. 2) Coronary arterial stenoses of 50-70% of greater reduction of luminal diameter involve most frequently the proximal portion of the major vessels. Coronary artery disease is multivessel in nature in 80% of cases. In single vessel disease the left anterior descending artery is involved most frequently. 3) The left main coronary artery is moderately to severely obstructed less frequently in individuals with left (2%) as compared to right (8%) and mixed (10%) systems. Otherwise, the distribution of coronary artery disease is similar in right, mixed, and left systems. 4) Coronary artery disease is a diffuse rather than a focal process. As demonstrated by coronary arteriography, patients with coronary artery disease have smaller vessels throughout the arterial tree as compared with individuals free of evident coronary atherosclerosis. 相似文献
