in this paper, we describe a case of an aneurysmal circumflex artery connected to the coronary sinus through a fistula in a 40-year-old man with a two-year history of palpitation and chest pain. we discussed surgical management for patients with coronary artery fistula (caf), particularly for asymptomatic patients with a small left-to-right shunt .

Objective Biochemical indicators such as N-terminal pro-brain type natriuretic peptide (NT pro-BNP) and high-sensitivity Creactive protein (hsCRP) predict mortality in acute coronary syndrome (ACS). However, little is known about the relationship of these factors with severity of coronary artery stenosis in patients with. Methods Three hundred and thirty-one subjects including 246 unstable angi...

OBJECTIVES We sought to determine endothelium-dependent vasodilator function in the brachial artery of patients with microvascular angina pectoris. BACKGROUND Previous studies suggest the presence of endothelial dysfunction of the coronary microcirculation in patients with microvascular angina pectoris. It is not known whether endothelial dysfunction in these patients is a generalized process...

large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...

The authors have reviewed the literature in search of the coexistence of single coronary artery with significant coronary artery disease. Two cases of single right coronary artery are described. In both, the anomalies were unsuspected and diagnosed roentgenographically in life. Both patients had angina pectoris, positive graded-exercise stress tests, and hemodynamically significant obstruction ...

OBJECTIVE Dysfunction of cardiac autonomic nerve system is considered as one of risk factors for coronary atherosclerotic heart disease. Heart rate variability (HRV) has been used to study the correlation between damage of coronary artery and dysfunction of autonomic nervous system. We hypothesize the correlation between damage of coronary artery and dysfunction of autonomic nervous system by H...

anomalous origin of the left coronary artery from the pulmonary artery (alcapa) is a rare congenital cardiac malformation. we report three cases of alcapa who survived to adulthood. the first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with alcapa using cardiac catheterization and coronary computed tomographic angiography (cta). the second case was a 30-...

OBJECTIVE Plaque rupture may be the local expression of a widespread coronary instability. This study aimed to investigate: (1) the prevalence and characteristics of nonculprit plaque rupture; (2) the pancoronary atherosclerotic phenotype in patients with and without nonculprit plaque rupture; and (3) the prevalence and predictors of multiple plaque ruptures. APPROACH AND RESULTS Six hundred ...

Anomalies of the coronary arteries are uncommon and often asymptomatic. Double right coronary artery (RCA) is a very rare coronary anomaly. So far, the number of reported cases of double RCA is low. We describe a case of a 50-year-old female patient hospitalised with the diagnosis of unstable angina pectoris. RCA injection showed filling of two separately originating RCA, coursing towards the r...

Patients who survive an acute myocardiac infarction (AMI) have significant coronary disease and are at risk for angina pectoris, recurrent myocardiac infarction and sudden death. This study provides data gathered prospectively for 106 patients surviving myocardial infarction who had coronary arteriography, left ventriculography and 24-hour electrocadiographic recordings before hospital discharg...
