Purpose
Coronary spasm is frequently found in patients with angina and unobstructed coronaries. The pathophysiology is incompletely understood, although sex differences have been described. Often a positive family history (PFH) is encountered. We assessed the relationship between sex, coronary spasm, and a PFH for cardiovascular disease.Methods
This single-center observational study recruited 415 stable angina patients with unobstructed coronaries (no stenosis >50%) between 2008 and 2011 (mean [SD] age, 62 [10] years; 38% men). Patients were referred for angiography because of signs and symptoms of myocardial ischemia. Intracoronary acetylcholine (ACh) testing was performed in all patients according to a standardized protocol. Risk factor assessment included hypertension, hypercholesterolemia, diabetes, smoking, and a PFH. The latter was defined as a first-degree relative with myocardial infarction or stroke. Statistical analysis involved comparison of categorical and continuous variables. Multivariable analysis aimed at identifying predictors for a pathologic ACh testing, microvascular spasm, and a PFH.Findings
Epicardial spasm was found in 33% of patients and microvascular spasm in 30% of patients. A pathologic ACh test was more frequent in women than in men (72% vs 49%; P < 0.0005). A PFH was found in 55% of patients with significantly more women than men (61% vs 45%; P?=?0.001). Among patients with epicardial spasm, women had a PFH significantly more often than men (66% vs 43%; P?=?0.006). The latter difference was not found when comparing women and men with microvascular spasm.Implications
There is a female preponderance among patients with angina and unobstructed coronaries. ACh testing enables detection of coronary spasm. Epicardial spasm in women is associated with a PFH. 相似文献6.

The recent technical advances in magnetic resonance imaging (MRI) and multislice computed tomography (MSCT) have led to a routine use of both methods in clinical cardiology. MRI is established for the diagnosis of complex congenital heart disease, aortic and pericardial disease as well as cardiac tumours. New indications include the diagnosis of myocardial infarction and inflammatory heart disease as well as myocardial perfusion measurements. CT is used for the diagnosis of coronary calcification for risk stratification. Moreover, stenoses of the coronary arteries and bypass grafts can be depicted using contrast enhanced multi-slice CT in selected patients. Training of cardiologists in the field of MRI has been defined by the Deutsche Arztetag in 2003 and demands 24 months of full-time training. At least 12 months must be spent in a department of radiology. Alternatively, the approach of the Landes?rztekammer Baden-Württemberg is presented. 相似文献

Myocarditis is an inflammatory disease of the heart frequently resulting from viral infections and/or post-viral immune-mediated responses. It is one of the important causes of dilated cardiomyopathy worldwide. The diagnosis is presumed on clinical presentation and noninvasive diagnostic methods such as cardiovascular magnetic resonance imaging. Endomyocardial biopsy remains the gold standard for in vivo diagnosis of myocarditis. The therapeutic and prognostic benefits of endomyocardial biopsy results have recently been demonstrated in several clinical trials. Although remarkable advances in diagnosis, understanding of pathophysiological mechanisms, and treatment of acute myocarditis were gained during the last years, no standard treatment strategies could be defined as yet, apart from standard heart failure therapy and physical rest. In severe cases, mechanical support or heart transplantation may become necessary. There is some evidence that immunosuppressive and immunomodulating therapy are effective for chronic, virus-negative inflammatory cardiomyopathy. Further investigations by controlled, randomized studies are needed to definitively determine their role in the treatment of myocarditis. 相似文献
