Extracorporeal Shock Wave Therapy for Coronary Artery Disease: Relationship of Symptom Amelioration and Ischemia Improvement

Objective(s): The current management of coronary artery disease (CAD) relies on three major therapeutic options, namely medication, percutaneous coronary intervention (PCI), and coronary artery bypass grafting (CABG). However, severe CAD that is not indicated for PCI or CABG still bears a poor prognosis due to the lack of effective treatments. In 2006, extracorporeal cardiac shock wave (SW) the...

Serial Myocardial Imaging after a Single Dose of Thallium-201

Although thallium-201 exercise scintigraphy has been established for the detection of myocardial ischemia and viability, little is known regarding the myocardial thallium-201 kinetics during angioplasty. Herein, we report a 77-year old man with angina pectoris, in whom serial myocardial imaging after a single dose of thallium-201 was helpful in identifying not only the culprit lesion and myocar...

Inhibiting miR-155 protects against myocardial ischemia/reperfusion injury via targeted regulation of HIF-1α in rats

Objective(s): The aim of this study was to identify the role of miR-155 in the myocardial ischemia/reperfusion (I/R) injury through targeting hypoxia-inducible factor 1-alpha (HIF-1α). Materials and Methods: We constructed rat models with myocardial I/R injury and H9C2 cell models with hypoxia/reoxygenation (H/R) damage. Anti-miR-155 and...

Contribution of the ST Elevation/T-Wave Normalization in Q-Wave Leads During Routine, Pre-Discharge Treadmill Exercise Test to Patient Management and Risk Stratification After Acute Myocardial Infarction A 2.5-Year Follow-Up Study

OBJECTIVES This study investigated whether ST-segment elevation and T-wave normalization (TWN) in Q-wave leads on pre-discharge exercise electrocardiogram (ECG) can contribute to patient management after a recent myocardial infarction (MI). BACKGROUND The clinical relevance of these exercise ECG changes remains controversial despite accumulating evidence of their association with myocardial via...

بررسی میزان QT dispersion استراحت و استرس در افراد غیر ایسکمیک و افراد ایسکمیک با شدت‌های مختلف

Abstract Background: The correlation between QT dispersion (QTd) and myocardial ischemia is controversial. The main purpose of current study was to investigate the relationship between QTd and the severity and extent of myocardial ischemia. Methods: In this cross sectional study, 100 patients with suspected coronary artery diseases (CAD) were studied. Based on the results of the myocardial ...

Clinical value and severity of myocardial perfusion defects in asymptomatic diabetic patients with negative or weakly positive exercise treadmill test

Objective: Although coronary artery disease (CAD) is the leading cause of death in type 2 diabetic patients, it is frequently asymptomatic. Myocardial perfusion imaging (MPI) is reported to show ischemia in a significant number of asymptomatic diabetic patients. We studied the prevalence and severity of myocardial perfusion defects in asymptomatic diabetic patients and its clinical impact. Meth...
