Aims: We aimed to study survival and causes of death in patients with ST-elevation acute coronary syndrome (STE-ACS) with and without obstructive coronary artery disease (CAD). Methods and results: We included 4793 consecutive patients with STE-ACS triaged for acute coronary angiography at a large cardiac invasive centre (2009-2014). Of these, 88% had obstructive CAD (stenosis ≥50%), 6% had non-obstructive CAD (stenosis 1-49%), and 5% had normal coronary arteries...

Aims: Total occlusion (TO) of the culprit artery usually presents with ST-elevation myocardial infarction. A subset of patients with TO present as non-ST segment elevation myocardial infarction (NSTEMI) without classic ST-elevation on the electrocardiogram. This may lead to delay in identification of these patients and further management. We performed a meta-analysis to estimate the difference in outcomes between totally occluded and non-occluded culprit arteries in patients with NSTEMI...

BACKGROUND: Acute cerebral incidents have been correlated with cardiac manifestations. Specifically, subarachnoid hemorrhage has been correlated with a syndrome described as neurogenic stress cardiomyopathy and mimics acute coronary syndrome. CASE REPORT: A 55-year-old woman presented at the Emergency Department of our hospital complaining of vomiting and headache of sudden onset. Computed tomography angiography revealed a ruptured aneurysm at the tip of the basilar artery and the patient underwent a successful complete embolism of the sac of the aneurysm...

BACKGROUND AND OBJECTIVE: With aging, the progression of atherosclerosis in the coronary arteries is expected. The Medtronic™ self-expandable aortic bioprosthetic valve is deployed in the supra-annular position, and it has been challenging to selectively engage coronary arteries post-transcatheter aortic valve replacement (TAVR) even though there are diamond-shaped spaces in the mesh frame within the valve. Given the scarcity of data, we analyzed angiographic and clinical data from all patients requiring coronary angiography (CA) or intervention post-TAVR...

There are over 300,000 out-of-hospital cardiac arrests (OOHCA) in the United States each year, and the long-term survival rate is less than 10%. Despite improvements in postarrest management, the greatest drop-off in survival occurs during hospitalization, mostly due to myocardial dysfunction and neurological injury. Coronary artery disease is common in postcardiac arrest patients, with an incidence of approximately 60-80%. In patients with a chest pain syndrome and an ST-segment-elevation myocardial infarction pattern evident on the presenting electrocardiogram, immediate revascularization is recommended by cardiovascular societies due to established mortality benefits...

A 42-year-old woman presented to the emergency department with chest pain. Acute coronary syndrome was ruled out. During dobutamine stress echocardiography (DSE), she developed chest pain and inferior ST elevation. Emergent coronary angiography revealed no culprit lesions but did show an anomalous right coronary artery (RCA). Coronary CT angiography (CCTA) confirmed an anomalous RCA arising from the left coronary cusp with a slit-like ostium and interarterial course (ARCA-LCC-IA). Herein, we review the extant literature on ARCA-LCC-IA, its clinical presentation, the vital role of CTA and MRI in its diagnosis, as well as challenges and controversies surrounding management...

BACKGROUND: There is paucity of data concerning the optimal revascularization in patients with multivessel coronary artery disease (CAD) presenting non-ST-segment elevation acute coronary syndrome (NSTE-ACS). The aim was to evaluate long-term outcomes of patients with multivessel CAD presenting NSTE-ACS depending on the management after coronary angiography. METHODS: 3,166 patients with NSTE-ACS hospitalized between 2006-2014 were screened. After exclusions, 1,342 patients were enrolled with multivessel CAD and were divided depending on their management after coronary angiography; the medical-only therapy group (n = 91), the PCI group (n = 1,122), the CABG group (n = 129)...

Coronary artery disease (CAD) has a complex etiology involving numerous environmental and genetic factors of disease risk. To date, the genetic 9p21 locus represents the most robust genetic finding for prevalent and incident CAD. However, limited information is available on the genetic background of the severity and distribution of CAD. CAD manifests itself as stable CAD or acute coronary syndrome. The Gensini score quantifies the extent CAD but requires coronary angiography. Here, we aimed to identify novel genetic variants associated with Gensini score severity and distribution of CAD...

Chronic kidney disease (CKD) is an important risk factor for coronary artery disease, yet patients with CKD are less likely to undergo coronary angiography and percutaneous coronary intervention (PCI). We retrospectively analyzed the 2006-2012 National Inpatient Sample Database to examine the temporal trends in coronary angiography and PCI among patients without CKD, with advanced CKD (CKD III-V), and with end-stage renal disease (ESRD) presenting with unstable angina/non-ST elevation myocardial infarction (NSTE-ACS) and ST-elevation myocardial infarction (STEMI)...

An 83-year-old man presented with recurrent acute coronary syndrome (ACS) at the left main coronary artery (LMCA) complicated with ostial chronic total occlusion (CTO) in the right coronary artery (RCA) (RCA-CTO). At the first LMCA-ACS approximately 1 year earlier, he had undergone LMCA-crossover stenting with a biolimus-eluting stent in the presence of RCA-CTO. At the second LMCA-ACS, we angiographically confirmed severe in-stent restenosis in the distal LMCA, in addition to angled severe stenosis in the just proximal LCx, and performed primary PCI for the LMCA bifurcation lesion under intra-aortic balloon pumping support...

Electrocardiographic changes resulting from apical hypertrophic cardiomyopathy may mimic an acute coronary syndrome. A 67-year-old Sudanese male without cardiac risk factors presented to hospital with chest pain and electrocardiographic findings of septal ST-segment elevation, ST-segment depression in V4-V6, and diffuse T-wave inversion. He was treated as an acute ST-elevation myocardial infarction with thrombolytics. There was no cardiac biomarker rise and coronary angiography did not reveal evidence of significant coronary arterial disease...

OBJECTIVES: To assess, whether cardiac catheterization via radial access prevents contrast-induced nephropathy. BACKGROUND: Contrast-induced nephropathy (CIN) is a major clinical problem which accounts for more than 10% of acute kidney injury cases in hospitalized patients. Protective measures such as the infusion of isotonic saline solution or acetylcysteine have not consistently been proven to prevent acute kidney injury (AKI). However, there is growing evidence that radial access for coronary angiography and coronary intervention is associated with a lower incidence of AKI compared to femoral access...

BACKGROUND: Most patients presenting to the emergency department (ED) with suspected acute coronary syndrome (ACS) undergo noninvasive cardiac testing with a low diagnostic yield. We determined whether a combination of high-sensitivity cardiac troponin I (hs-cTnI) and cardiovascular risk factors might improve selection of patients for cardiac testing. METHODS: We included patients from the Rule Out Myocardial Infarction/Ischemia Using Computer Assisted Tomography (ROMICAT) I and II trials who presented to the ED with acute chest pain and were referred for cardiac testing...
