Background: Myocardial infarction remains one the leading causes of mortality and morbidity involves a high cost care. Early prediction can be helpful in preventing development myocardial with appropriate diagnosis treatment. Artificial neural networks have opened new horizons learning about natural history diseases predicting cardiac disease. Methods: A total 935 patients chest pain nondiagnostic electrocardiogram (ECG) were enrolled followed for 2 weeks two groups based on appearance...

Introduction: Myocardial bridge (MB) is a segment of major epicardial coronary artery that goes intramurally under overlying myocardium. Complications have been reported during or after stent implantation particularly perforation. The aim this study was to determine histological differences between proximal left anterior descending (LAD) and the tunneled may possible role in increased risk perforation percutaneous intervention. Methods: Twenty specimens MB were obtained from dissection 45...

Introduction: Myocardial bridge (MB) is a congenital anomaly in which segment of coronary artery surrounded by myocardium. In our study, we want to use conventional angiography (CCA) describe morphologic characteristics MB (unidentified or identified) the patients with documented evidence computed tomography (CCTA). Methods: The present study was designed as cross-sectional and conducted on 47 CCTA, who were referred Nemazee Faghihi hospitals for performing during one year period. We...

Successful closure of atrial septal defect (ASD) improves patients' functional class and exercise capacity. In this study we evaluate the safety feasibility percutaneous device ASDs.Two hundred fifty six patients with significant ASD according to our criteria were enrolled. The treated using nitinol wire mesh transcatheter devices. Complications followed for a median 2.5 years.Success rate was 98.4% 3 unsuccessful cases mean hospital stay 1.007 ± 0.0004 days. Complication 7.42%. Size right...

We report the case of a 49-year-old female patient who underwent percutaneous coronary intervention right and posterior descending arteries complicated with guidewire-induced artery perforation. successfully managed sealed this perforation through embolization balloon pieces into target vessel. (Level Difficulty: Advanced.).

Summary Cloud computing as a new model of delivering IT services on the Internet has attained high attention recently. In this paradigm, efficient service management causes quality provided services. Scheduling one most important duties is key problem in cloud that affects total system performance. cases, meta‐heuristic methods are used for optimizing scheduling issues instead traditional methods. One influential evolutionary algorithms complicated problems non‐dominated sorting particle...

Spontaneous coronary artery vasospasm is one of the important causes acute chest pain syndromes. The diagnosis diffuse multifocal spasm can be quite challenging and it could easily mistaken for disease. use intracoronary nitroglycerin relieve reveal real extent Herein we present a case presenting with myocardial infarction due to severe that had even received fibrinolytic therapy. Multiple narrowing was shown during angiography patient scheduled percutaneous intervention (PCI). But after...

The intensive care unit (ICU) is a complex, dynamic, high stress and time-sensitive place. While variety of rules regulations provided to reduce medication errors in recent years, many studies have emphasized that still happen.The purpose this investigation predict, reveal assess among surgical (SICU) nurses.This study was performed one the public hospitals Shiraz, namely Shahid Faghihi hospital. human error assessment reduction technique (HEART) method adopted measure ICU.Findings indicate...

Abstract Currently, the best treatment strategy for patients with a high‐normal blood pressure (prehypertension) is not known. The authors aimed to determine whether pharmacological reduction of systolic (SBP) normal level (<120 mm Hg) would prevent cardiac morbidity and mortality in prehypertensive patients. In this secondary analysis, obtained data from SPRINT National Heart, Lung, Blood Institute repository center. Among 9361 enrolled SPRINT, 289 high‐risk (ASCVD risk = 24.8% ± 13.0...

One of the most common causes death in world is coronary artery disease (CAD). Estrogen, important early sex hormones women, plays an role risk reduction cardiovascular (CVD). Expression estrogen as well its receptors including receptor alpha (ER1) and beta (ER2) might have association with severity or complexity CAD. Since articles focused on relationship between ER1 gene polymorphism CAD, this study, we aimed to evaluate two ER2 polymorphisms, rs4986938 (AluI) rs1256049 (RsaI), CAD.148...

Human leukocyte antigen (HLA) complex is a gene family involved in presentation associated with protection or susceptibility to inflammatory, infectious and autoimmune diseases. Atherosclerosis chronic inflammatory disease which HLA molecules play role the initiation development of through self foreign antigens T cells.To investigate association HLA-DRB1 alleles atherosclerosis sample southwestern Iranians.We performed an analytical cross-sectional study involving 96 patients 72 controls....

The subclavian steal syndrome (SSS), also called steno-occlusive disease, is defined as reversal of the vertebral artery flow secondary to significant hemodynamically ipsilateral occlusion or stenosis proximal artery. It usually seen atherosclerosis and aberrant right (ARSA), resulting in SSS which even less common. Aberrant a kind vascular anomaly associated with coarctation aorta (CoA). originates from descending distal site CoA. Here, we present young man who was case ARSA He developed...

Abstract Background Clinical importance of aVR lead‐related changes in predicting the prognosis acute myocardial infarction remains uncertain. The present study aimed to assess value ST‐segment lead and outcome sequels first episode elevation infarction. Methods This prospective cohort was conducted on patients suffering underwent percutaneous coronary intervention. Information collected through hospital‐recorded files reading. electrocardiogram (ECG) taken from upon entering hospital...

Iatrogenic aortocoronary dissection and ostial coronary avulsion are rare devastating complications of Percutaneous Coronary Intervention (PCI), which mandate a challenging management.Herein, we described case right in dwarf woman with chronic total occlusion the vessel during PCI discussed about results pitfalls.

We read the article “Simultaneous thrombosis of multiple coronary arteries in a patient with rheumatoid arthritis” by Kalayci et al1 great interest. The authors presented arthritis treated methotrexate developing ST segment elevation myocardial infarction. commend for this interesting report and want to make some comments. Between three options had at time performing angiography, it was wisest choice administer fibrinolytic therapy; but other causes simultaneous should be ruled out. It...

: A 60-year-old man was referred with a 1-month history of angina and dyspnea to cardiology clinic. In physical examination, there rough, low-pitched crescendodecrescendo systolic murmur that best heard at the second intercostal space right upper sternal border

The incidence of guiding catheter tip fracture, is quite rare during percutaneous coronary interventions (PCI). Retained broken in artery and circulation can result serious complications such as thrombosis, embolism, acute occlusion myocardial infarction, arrhythmias sepsis. It mandatory to remove the fractured soon possible avoid these complications. Transcatheter removal treatment choice. If failed, surgical intervention advised.

Abstract Background There is some evidence of the association between ST‐segment elevation in V4R chest lead and likelihood anterior wall myocardial infarction; however, link this phenomenon with location severity coronary involvements such patients remains uncertain. We aimed to investigate leads infarction also its effect on prognosis as well detection prediction arterial stenosis angiography. Methods Data collection was performed by reviewing hospital recorded files 195 patients’...
