BACKGROUND While use of P2Y12 receptor inhibitor is recommended by guidelines, few studies have examined its effectiveness among older non-ST-segment elevation myocardial infarction patients who did not undergo coronary revascularization. METHODS AND RESULTS We included unrevascularized non-ST-segment elevation myocardial infarction patients ≥65 years discharged home from 463 ACTION Registry-...
OBJECTIVE The aim of the present study was to investigate the association of neutrophil/lymphocyte ratio (NLR) with coronary artery calcium score (CACS) and obstructive coronary artery disease (CAD) detected by multislice computed tomography (MSCT) angiography in type 2 diabetes mellitus (T2DM) patients. METHODS Two hundred and ninety-two T2DM patients, who were either asymptomatic or symptom...
BACKGROUND Computed tomography-adapted Leaman score (CT-LeSc) was developed to quantify coronary CT angiography information about atherosclerotic burden (lesion localization, stenosis degree, and plaque composition). The objective of the study is to evaluate CT-LeSc long-term prognostic value in patients with suspected coronary artery disease (CAD). METHODS AND RESULTS Single-center prospecti...
BACKGROUND TIMI frame count (TFC) predicts outcomes in patients with obstructive coronary artery disease (CAD); it remains unclear whether TFC predicts outcomes in patients without obstructive CAD. METHODS TFC was determined in a sample of women with no obstructive CAD enrolled in the Women's Ischemia Syndrome Evaluation (WISE) study. Because TFC is known to be higher in the left anterior des...
Cardiovascular disease is the leading cause of death worldwide, and coronary artery disease (CAD) is the most common type of heart disease. Up to 20–30% of patients presenting with chest discomfort demonstrate no signs of obstructive CAD. In the field of invasive cardiology more than 50% of the patients undergoing coronary angiography for non-acute chest pain have normal or near normal coronary...
OBJECTIVES The current meta-analysis aimed to evaluate the diagnostic performance of hybrid cardiac imaging techniques compared with stand-alone coronary computed tomography angiography (CTA) for assessment of obstructive coronary artery disease (CAD). BACKGROUND The usefulness of coronary CTA for detecting obstructive CAD remains suboptimal at present. Myocardial perfusion imaging encompasse...
OBJECTIVES The aim of this study was to perform a head-to-head comparison between multi-slice computed tomography (MSCT) and myocardial perfusion imaging (MPI) in patients with an intermediate likelihood of coronary artery disease (CAD) and to compare non-invasive findings to invasive coronary angiography. BACKGROUND Multi-slice computed tomography detects atherosclerosis, whereas MPI detects...
Cardiovascular disease (CAD) screening in asymptomatic patients with diabetes mellitus is controversial. An exercise stress test is a safe and effective initial testing for Ischemic Heart Disease (IHD) screening. Treadmill stress test is not the best screening method for a particular patient who is not able to exercise, abnormal electrocardiogram (ECG) or positive exercise treadmill test (ETT) ...
AIMS In symptomatic patients with suspected coronary artery disease (CAD), computed tomographic angiography (CTA) improves patient selection for invasive coronary angiography (ICA) compared with functional testing. The impact of measuring fractional flow reserve by CTA (FFRCT) is unknown. METHODS AND RESULTS At 11 sites, 584 patients with new onset chest pain were prospectively assigned to re...
conclusions the mechanism of mid-variant of dobutamine-induced stress cardiomyopathy remains unclear. we think that multiple mechanisms are involved and this risk should be considered in patients with comorbid psychiatric conditions and with use of centrally acting stimulants. case presentation we report a 48-year-old female with intermittent chest pain. her physical exam, cardiac enzymes and t...
