Fibrinogen (Fib) is a useful marker for predicting the severity of coronary artery disease (CAD) in adult population. However, whether Fib can be a predictor for the presence and severity of CAD in very young MI patients (≤35 years old) remains to be determined. A total of 418 males from 61,863 patients with MI who were under 35 years old were sequentially recruited in our study. The patients were divided into two main groups and three subgroups according to coronary angiograph and Gensini score (GS) system: no coronary artery stenosis (group A), the results of the coronary artery stenosis (group B); low GS, intermediate GS and high GS...

Left main coronary artery (LMCA) thrombosis with acute myocardial infarction is a rare condition with very high mortality. The low incidence of this condition and exclusion of patients with LMCA thrombosis from clinical trials prevent the development of optimal management strategy in these patients. Therefore, there are no clear-cut guidelines describing an evidence-based approach for this condition. We describe a patient with LMCA thrombosis presenting with acute myocardial infarction, who was found to have hypercoagulable state related to homocysteinemia on further work-up...

This meta-analysis compared IVUS-guided with angiography-guided PCI to determine the effect of IVUS on the mortality in patients with LM CAD. Current guidelines recommend intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with left main coronary artery disease (LM CAD; Class IIa, level of evidence B). A systematic search of the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases was conducted to identify randomized or non-randomized studies comparing IVUS-guided PCI with angiography-guided PCI in LM CAD...

During the last 25 years angiotensin-converting enzyme inhibitors spectacularly conquered the field of cardiovascular diseases therapy. Nevertheless, lack of new studies concerning side effects associated with their chronic administration seems to be rather confusing. In our previous research, we proved that the main furnidipines' metabolite (M-2) possess multiple cardioprotective actions. Currently, we compared effects of post-infarction long-term oral treatment with M-2 and captopril on hemodynamic parameters and "ischemic cardiomyopathy" development in rats...

OBJECTIVES: The main reason for aortic repair failures is recurrent annular dilatation. The fibrous portion of left ventricular outflow tract dilates. A novel device was designed to tackle this problem. METHODS: The device consists of an internal ring applied at the aortic annulus plus an external flexible band at the level of the aortic root. The internal ring has a semi-rigid portion (40%, placed at ventriculo-arterial junction) and a flexible portion to allow it to conform along the curves of the non-coronary/right coronary leaflet and right coronary/left coronary leaflet commissures...

We present a case of transcatheter valve-in-valve replacement performed because of structural valve deterioration of a subcoronary implanted stentless aortic bioprosthesis. A 23-mm self-expandable transcatheter heart valve (THV) with supraannular seating was chosen. The procedure was performed with the patient under conscious sedation. After anchoring and partial valve deployment, the patient experienced an acute onset of angina. The angiogram showed left main coronary artery obstruction. Prompt resheathing and retrieval of the THV was performed, and the procedure was aborted...

PURPOSE: To evaluate choroidal thickness (CTh) in patients with coronary artery disease (CAD) compared to healthy controls. DESIGN: Cross-sectional. METHODS: Setting: Ambulatory clinic of a large city hospital. Patient population: Thirty-four patients had documented CAD, defined as history of >50% obstruction in at least one coronary artery on cardiac catheterization, positive stress test, ST elevation myocardial infarction, or revascularization procedure...

BACKGROUND: We compared direct stenting (DS) with conventional stenting (CS) - i.e., stenting after predilation - during primary percutaneous coronary intervention (P-PCI) in terms of procedural results and long-term mortality in patients with ST-elevated myocardial infarction (STEMI). METHODS: We retrospectively analyzed 2306 patients (mean age 59 years, 22% female) who underwent P‑PCI within 12 h of symptom onset. Patients were then followed up prospectively for clinical events...

BACKGROUND: The risk factors along with demographic and angiographic features associated with aorto-ostial atherosclerotic coronary artery disease usually differ from that of non-aorto-ostial atherosclerotic coronary artery disease. OBJECTIVES: This study was designed to evaluate etiology of aorto-ostial atherosclerotic coronary artery disease involving left main coronary artery (LMCA), right coronary artery or both with consideration of clinical risk factors, demographic and angiographic features...

INTRODUCTION: Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare but severe congenital cardiac malformation. The prognosis mainly depends on the early and accurate diagnosis and treatment. However, without a typical and specific clinical manifestation in early stage, ALCAPA has a higher rate of false initial diagnosis. DIAGNOSTIC AND THERAPEUTIC PROCEDURE: Three infants with impaired left ventricle (LV) function, LV enlargement, mitral valve regurgitation (MR), and LV endocardium thickness were initially diagnosed as endocardial fibroelastosis (EFE)...

OBJECTIVES: To quantify the radiation dose reduction achievable by minimizing z-axis coverage in 320-detector coronary computed tomography angiography (CCTA). METHODS: We retrospectively reviewed 130 CCTAs performed on 320-detector CT that offers up to 16cm z-axis coverage (adjustable in 2cm increments), allowing complete coverage of the heart in a single gantry rotation. For each CT we obtained the radiation dose (CTDIvol and DLP), measured the z-axis field of view and measured the craniocaudal cardiac size (distance from the left main coronary artery to the cardiac apex)...

REVIEW
Semhar Z Tewelde, Amal Mattu, William J Brady
Less than half of patients with a chest pain history indicative of acute coronary syndrome have a diagnostic electrocardiogram (ECG) on initial presentation to the emergency department. The physician must dissect the ECG for elusive, but perilous, characteristics that are often missed by machine analysis. ST depression is interpreted and often suggestive of ischemia; however, when exclusive to leads V1-V3 with concomitant tall R waves and upright T waves, a posterior infarction should first and foremost be suspected...

For nearly half a century, coronary artery bypass grafting has been the standard treatment for patients with obstructive left main coronary artery (LMCA) disease. However, there has been considerable evolution in the field of percutaneous coronary intervention, and especially, percutaneous coronary intervention for LMCA disease has been rapidly expanded with adoption of drug-eluting stents. Some, but not all randomized trials, have shown that percutaneous coronary intervention with drug-eluting stents might be a suitable alternative for selected patients with LMCA disease instead of bypass surgery...

The left main coronary artery (LMCA) is responsible for supplying the majority of the left ventricular myocardium. Visual estimation of stenosis severity on angiography has major limitations and methods to assess functional significance, such as Fractional Flow Reserve (FFR), have been shown to yield better outcomes but major trials examining the use of such physiological indices have excluded LMCA disease to date. Furthermore, LMCA disease commonly co-exists with downstream disease, which complicates interpretation of coronary physiological data...

Objective We aimed to determine the capacity of drug-eluting stent (DES) over-expansion in left main coronary artery disease. Methods Left main interventions with the largest available DES platforms (4.0 mm) and post-dilation performed with large non-compliant balloons (≥ 4.5 mm) were included. Maximal stent diameter (mm) and area (mm(2)) were measured using post-intervention intravascular ultrasound (IVUS). Stent diameter and area were calculated with the balloon diameter and inflation pressure. The diameter and area expansion indices were defined as follows: maximal/calculated stent diameter and maximal/calculated stent area, respectively...
