Anginal chest pain in patients with angiographically normal coronary arteries may be caused by a limited coronary flow response to stress because of abnormal function of the coronary microcirculation (microvascular angina). Studies of forearm arterial function suggested that patients with
BACKGROUND
A sizeable proportion of patients with primary stable microvascular angina (MVA; exercise-induced angina, positive exercise stress test [EST], normal coronary arteries) have recurrent symptoms during follow-up. There have been no previous studies, however, on the long-term results of EST
In a series of 120 hypertensive patients, 60 were found to have echocardiographic left ventricular (LV) hypertrophy (Devereux's method). Of these, 18 (30%) had typical stress-induced angina and underwent coronary angiography, which showed that 11 (61%) had normal coronary arteries, and 7 (39%) (p <
OBJECTIVE
Takayasu arteritis (TA), a systemic vasculitis typically occurring in female patients aged ≤40, can affect coronary arteries and cause ischemic heart disease (IHD). In this study, we investigated the prevalence of TA in young women presenting with IHD in the Emergency
Coronary artery ectasia is characterized by an abnormal dilatation of the coronary arteries. Coronary artery ectasia is observed in 3-8% of patients undergoing coronary angiography and sometimes leads to acute coronary syndrome regardless of the presence or absence of coronary stenosis OBJECTIVE
This study aimed at determining the prevalence of epicardial and microvascular coronary spasm in patients with anginal symptoms, despite angiographically normal coronary arteries.
BACKGROUND
Despite a typical clinical presentation with exercise-related anginal symptoms (chest pain or
Determine the prevalence and correlates of microvascular and vasospastic angina in patients with symptoms and signs of ischemia but no obstructive coronary artery disease (INOCA).METHODS
Three hundred ninety-one patients with angina were enrolled at 2
