Background: The aim of this study was to assess the relationship between hypertension and aldosterone-renin ratio (ARR) with the severity of coronary artery disease (CAD). Methods: This cross-sectional study was performed on non-diabetic patients who were candidate for coronary angiography in Shafa hospital in Kerman in 2017. The levels of active renin and ald...

Background: Slow coronary flow (SCF) is defined as a condition in which in spite of no evidence of coronary occlusion or stenosis in angiography, there is delayed pacification of the vessels after the injection of a contrast agent. There are several studies about electrocardiogram (ECG) changes in these patients, but changes like OLD MI, RBBB, LBBB, LVH and ST-T wave have not b...

Coronary air embolism is one of the inadvertent complications of coronary angiography. We report a case of unexpected massive right coronary air embolism during left coronary angiography with a JL4 diagnostic catheter. This report demonstrates that air embolism may occur in the contralateral coronary artery and therefore complete air aspiration must be ensured during coronary angiography.

background : st-elevation myocardial infarction (stemi) is a major cause of cardiovascular mortality worldwide. there are differences between very young patients with stemi and their older counterparts.   this study investigates the demographics and clinical findings in very young patients with stemi. methods: through a review of the angiography registry, 108 patients aged ≤ 35 years (group i) ...

background although the aim of cardiac computed tomographic angiography (cta) is to visualize the cardiac, coronary, and great vessels, portions of noncardiac structures such as lung, mediastinum, bones and abdomen are visible on the scan. some have suggested that the scans should be evaluated in all field of view. some other believe that reporting accidental findings can lead to unnecessary fo...

a 56 year old man was admitted to our center for further evaluation of typical chest pain of ten months' duration. selective coronary angiography was done and showed a sewing needle-like foreign body which was lying in very close proximity to the anatomic location of the right coronary artery. at operation two pieces of sewing needles were removed, one from the coronary sinus and the other...

Multislice CT angiography represents one of the most exciting technological revolutions in cardiac imaging and it has been increasingly used in the diagnosis of coronary artery disease. Rapid improvements in multislice CT scanners over the last decade have allowed this technique to become a potentially effective alternative to invasive coronary angiography in patients with suspected coronary ar...

BACKGROUND Multi-slice computed tomography (MSCT) is a fast-growing technology that permits a non-invasive, yet reliable, assessment of coronary atherosclerosis. We sought to explore the diagnostic accuracy of MSCT angiography in the detection of significant stenosis of the left main coronary artery (LMCA) in a series of patients with an intermediate pre-test likelihood of coronary artery disea...

Invasive coronary angiography and computed tomography (CT) coronary angiography directly visualise coronary anatomy but do not provide information about the presence of inducible myocardial ischaemia. Due to its excellent negative predictive value CT coronary angiography is a suitable test to exclude significant coronary artery disease. However, given its high rate of false positive results par...
