Investigating the expression level of miR-17-3p, miR-101-3p, miR-335-3p, and miR-296-3p in the peripheral blood of patients with acute myocardial infarction.

The role of inflammation has been proven in acute myocardial infarction (AMI) pathogenesis. Due to the effect of NLRP3 gene expression in the inflammation process of MI, we aimed to explore the expression changes and diagnostic power of four inflammation-related miRNAs including miR-17-3p, miR-101-3p, miR-335-3p, miR-296-3p and their potential target, NLRP3, in ST-segment elevation myocardial infarction (STEMI), and non-STEMI (NSTEMI) patients as two major classes of AMI. The expression level of these genes were evaluated in 300 participants equally divided into three groups of STEMI, NSTEMI, and control using quantitative real-time PCR.

The Association Between Hematologic Indices with TIMI Flow in STEMI Patients who Undergo Primary Percutaneous Coronary Intervention.

Background: The Primary Percutaneous Coronary Intervention (PPCI) is the preferred therapeutic strategy for patients who experienced ST-Elevation Myocardial Infarction (STEMI).

Objective: We aimed to evaluate the association of hematological indices, including hemoglobin level, platelets, White Blood Cells (WBCs) count, and MPV before PPCI with the TIMI grade flow after PPCI.

Methods: STEMI patients who experienced PPCI were included in the present retrospective crosssectional study.

Visual-Functional Mismatch Between Coronary Angiography, Fractional Flow Reserve, and Quantitative Coronary Angiography.

Anatomical and functional mismatches are not uncommon in the assessment of coronary lesions. The aim of this study was to identify clinical and lesion-specific factors affecting angiographic, anatomical, and functional mismatch in intermediate coronary lesions. In patients who underwent coronary angiography for clinical reasons, fractional flow reserve (FFR), and quantitative coronary angiography (QCA) analyses for intermediate stenotic lesions were performed simultaneously.

Carotid artery stenting: a single-center experience.

Background: Carotid artery stenting is now used as an alternative to surgical endarterectomy. This study was done to assess the feasibility, safety, and immediate and late clinical outcomes in patients undergoing carotid stenting.

Methods: Between July 2008 and December 2009, a total of 40 patients (20 male, mean age: 65 ± 11 years, 19 symptomatic, and 90% high risk for endarterectomy) underwent carotid artery stenting with different embolic protection devices and carotid stents.

Isolated noncompaction of left ventricular myocardium with an unusual presentation of angina pectoris.

A 45-year-old man presented to the hospital with typical chest pain compatible with myocardial infarction. An electrocardiogram showed left bundle branch block. The patient underwent urgent coronary angiography, which revealed no significant coronary artery disease.

Angina induced by 5-fluorouracil infusion in a patient with normal coronaries.

This article reviews the occurrence of angina in patients treated with 5-fluorouracil (5-FU) without significant coronary artery disease. We present a case followed by a review of the literature. A 43-year-old man with a history of colon cancer developed typical angina during intravenous infusion of 5-FU.

Percutaneous treatment of spontaneous left main coronary artery dissection extending to the left anterior descending and circumflex arteries possibly triggered by thrombolytic therapy.

Spontaneous coronary artery dissection is a rare cause of myocardial infarction and the role of thrombolytic therapy in this setting is not known. A case of acute ST elevation myocardial infarction is presented, with initial positive response to thrombolytic therapy and subsequent marked worsening of ST elevation due to extensive dissection, possibly triggered by thrombolytic therapy, which was successfully treated with percutaneous coronary intervention.

Extrinsic compression of left main coronary artery by the pulmonary trunk secondary to pulmonary hypertension documented using 64-slice multidetector computed tomography coronary angiography.

Compression of left main coronary artery (LMCA) secondary to pulmonary trunk dilatation is a newly recognized entity that has been associated with severe pulmonary hypertension. In this paper we present a case of extrinsic compression of LMCA caused by dilated pulmonary trunk secondary to pulmonary hypertension documented using 64-slice multidetector computed tomography (MDCT) coronary angiography. This case is followed by a review of the literature.
