BACKGROUND ST-elevation myocardial infarction (STEMI) is a major cause of cardiovascular mortality worldwide. There are differences between very young patients with STEMI and their older counterparts. This study investigates the demographics and clinical findings in very young patients with STEMI. METHODS Through a review of the angiography registry, 108 patients aged ≤ 35 years (Group I) wer...
BACKGROUND Coronary computed tomography angiography (coronary CTA) can prognosticate outcomes in patients without modifiable risk factors over medium term follow-up. This ability was driven by major adverse cardiovascular events (MACE). OBJECTIVE Determine if coronary CTA could discriminate risk of mortality with longer term follow-up. In addition we sought to determine the long-term relation...
Several epidemiological studies have shown that the prevalence of ischemic heart disease is higher in occupational drivers than in people with other occupations. Although occupation categories can be surrogate measures for coronary risk factors, the relationships between taxi driving and severity of coronary heart disease (CHD) has not been investigated. Even more important, the contribution of...
background and objective: obstructive sleep apnea (osa) is frequent and in some degree it affects about 24% of male and 9% of female in middle age adults. this study aimed to assess the association between risk of osa and cad. materials and methods : this case-control study was performed among 184 patients with a history of coro- nary angiography in two catheter labs at hospitals in qom, iran. ...
BACKGROUND Coronary artery anomalies are rare, accounting for about 0.3-1.3% of patients undergoing diagnostic coronary angiography. Interventions in these cases are still rare, and therefore pose technical challenges during intervention. CT Angiography provides a non-invasive means of assessment of coronary artery disease and also shows the anatomy of the coronary tree. This helps in knowing t...
OBJECTIVE Dysfunction of cardiac autonomic nerve system is considered as one of risk factors for coronary atherosclerotic heart disease. Heart rate variability (HRV) has been used to study the correlation between damage of coronary artery and dysfunction of autonomic nervous system. We hypothesize the correlation between damage of coronary artery and dysfunction of autonomic nervous system by H...
coronary-cameral fistulas (ccfs) constitute a rare anomaly that can be incidentally detected during angiography. ccfs are solitary, large or small assemblies that originate from coronary arteries and enter one of the cardiac chambers. we describe a 29-year-old woman, who referred to our clinic with the chief complaints of palpitation, atypical chest pain, and dyspnea on exertion (functional cla...
Single right coronary artery with congenital absence of left coronary artery is one of the rarest coronary artery anomalies. Most coronary anomalies are asymptomatic and incidental findings. We report a case of single right coronary artery with congenital absence of left coronary artery detected by coronary CT angiography. Physical examination revealed a well-nourished female with a blood press...
BACKGROUND AND PURPOSE Identifying occult coronary artery stenosis may improve secondary prevention of stroke patients. The aim of this study was to derive and validate a simple score to predict severe occult coronary artery stenosis in stroke patients. METHODS We derived a score from a French hospital-based cohort of consecutive patients (n=300) who had an ischemic stroke or a transient isch...
BACKGROUND In this study, we investigated the feasibility of primary care physicians using carotid ultrasound to perform coronary artery disease screening in asymptomatic patients with multiple coronary risk factors. METHODS We retrospectively collected the data of 135 consecutive asymptomatic patients (mean age: 68.5 ± 8.4 years; male, 75%) who were referred to our institution due to abnorma...
