Background: Chronotropic incompetence has prognostic value of all-cause and cardiovascular mortality in both patients with asymptomatic and symptomatic ischemic heart disease (IHD), regardless of traditional risk factors. The aim of this study was to investigate the relationship between chronotropic response during exercise test and the development of ventricular arrhythmias. Methods: 153 pati...

Background and Objective: Depression is one of the most common psychological problems, which can elevate the risks of cardiovascular complications. This study was performed with the aim of retrospectively reviewing the relationship between these two illnesses in middle-aged people. Materials and Methods: In this case control study, 200 patients were randomly chosen as the case group from among...

Background: Inflammation and infectious agents such as Chlamydia pneumoniae have been associated with cardiovascular disease. Objective: To evaluate the serum high sensitivity C - reactive protein (hs-CRP) and antibodies against Chlamydia pneumoniae and Chlamydial heat shock protein-60 (Cp-HSP60) in patients with ischemic heart disease (IHD). Methods: 62 patients with IHD having either acute my...

discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...

aim and background: patients with ischemic heart disease in acute stage experienced great anxiety and in compared with patients had less anxiety were affected 5 times more to ischemia, re-infarction, tachycardia, arrhythmias and ventricular fibrillation.  excessive anxiety delays recovery and increases the probability of their death in the first month. numerous studies have shown that heart dis...

Background: Emergency department congestion is among the major barriers to receiving nursing care for high-priority conditions, like ischemic heart disease. Therefore, it can affect patients’ satisfaction with the quality of care. This study aimed to investigate satisfaction with emergency care among patients with ischemic heart disease. Methods: This cross-sectional study was conducted on 600...

Mitochondria play an important role in energy production for the cell. The proper function of a myocardial cell largely depends on the functional capacity of the mitochondria.  Therefore it is necessary to establish a novel and reliable method for a non-invasive assessment of mitochondrial function and metabolism in humans. Although originally designed for evaluating myocardial perfusion, 99mTc...
