INTRODUCTION Coronary artery anomalies are found in 0.6% to 1.55% of patients who undergo coronary angiography, and the increasing use of diagnostic coronary angiography is uncovering even more such abnormalities. We present a very unusual case of an anomalous origin of the left circumflex coronary artery (LCx) from the proximal right coronary artery (RCA). CASE PRESENTATION We present a case...

With the introduction of new surgical procedures an the development of new techniques of cardiac imaging, the normal anatomy, variations and anomalies of coronary arteries have assumed new significance. The coronary arteries may present several variations, in terms of both number and position. The incidence of all coronary anomalies is 0.23% in autopsy series and ranges between 0.3% and 12% in ...

PURPOSE Many patients admitted for acute myocardial infarction (AMI) have chronic renal insufficiency and erectile dysfunction (ED). This study aimed to evaluate the relationship between ED and the glomerular filtration rate (GFR) in patients with coronary artery disease. MATERIALS AND METHODS We studied 183 patients undergoing coronary angiography owing to AMI. The GFR was calculated and the...

The prevalence of coronary artery stenoses 2 70% or left main stenosis > 50% was evaluated in 20,391 patients who underwent angiography in the Coronary Artery Surgery Study from 1975-1979. After the patients with unstable angina or myocardial infarction were excluded, the disease prevalence in the 8157 patients with definite angina, probable angina, and nonspecific chest pain was 93%, 66% and 1...

BACKGROUND In 'real-world' patient populations undergoing coronary CT angiography (CCTA), it is unclear whether a correlation exists between gender, coronary artery calcium (CAC) score and subsequent referral for invasive coronary angiography and coronary revascularisation. We therefore investigated the relationship between gender, CAC and use of subsequent invasive coronary angiography and cor...

BACKGROUND Sublingual nitroglycerin (glyceryltrinitrate, GTN) capsules or isosorbide dinitrate (ISDN) spray are routinely used to treat anginal attacks and to vasodilate maximally the epicardial coronary arteries during coronary angiography. OBJECTIVE To compare the coronary vasodilatory effects of GTN capsules and ISDN spray with those induced by intracoronary GTN using quantitative coronary...

abstract introduction. cardiovascular disease is the most common cause of death in developed counteries and it’s morbidity and mortality is also increasing in asia. hypertension, hyperlipidemia and smoking are majore risk factors of atherosclerosis. in recent years infectious agents such as clamidia pneumoniae, helicobacter pylori and dental flora infections seems to be effective in development...

Background—Sublingual nitroglycerin (glyceryltrinitrate, GTN) capsules or isosorbide dinitrate (ISDN) spray are routinely used to treat anginal attacks and to vasodilate maximally the epicardial coronary arteries during coronary angiography. Objective—To compare the coronary vasodilatory eVects of GTN capsules and ISDN spray with those induced by intracoronary GTN using quantitative coronary an...

0 B J E C T IV E S: Our objective was to prospectively evaluate the diagnostic performance of the high-speed dual-source computed tomography scanner (DSCT), with an increased temporal resolution (83 ms), for the detection of significant coronary lesions (2": 50% lumen diameter reduction) in a clinically wide range of patients. BACK G R 0 UN D: Cardiac motion artifacts may decrease coronary imag...

conclusion our results indicate that dsct coronary angiography provides high diagnostic accuracy for the evaluation of cad patients during daily routine practice of a referral cardiovascular setting. background there are numerous studies that address the diagnostic value of dual-source computed tomography (dsct) as an alternative to conventional coronary angiography (cca). however, the benefit ...
