Coronary heart disease the most prevalent form of cardiovascular disease, results from the blockage of blood flow through arteries. The Myocardial Perfusion Scan (MPS) is considered a non-invasive method to assess the heart condition and provides valuable information, such as End Diastolic Volume (EDV), End Systolic Volume (ESV), Ejection Fraction (EF), Lung to Heart Ratio (LHR), and Transient Ischemic Dilatation (TID).
This study aimed to investigate changes in gated heart scan parameters to diagnose patients, who are candidates for heart surgery.
In this descriptive cross-sectional study, 40 patients who are candidates for heart surgery were enrolled to evaluate the relation between the parameters of the gated heart scan and the amount of ischemic area of the heart. After scanning the patients, TID, ESV, LHR, and EF and also the movements of the heart walls are examined and analyzed in these patients.
According to the results of the one-sample t-test showing a significant difference between the parameters, the results were within the normal range (-value<0.0001). Additionally, all patients showed changes in cardiac output and wall movement issues.
The evaluation of Myocardial Perfusion Scan (MPS) and gated heart scan parameters can provide an effective method for diagnosing patients who may require heart surgery.
冠心病是心血管疾病最常见的形式,由动脉血流阻塞引起。心肌灌注扫描(MPS)被认为是一种评估心脏状况的非侵入性方法,可提供有价值的信息,如舒张末期容积(EDV)、收缩末期容积(ESV)、射血分数(EF)、肺心比(LHR)和短暂性心肌缺血性扩张(TID)。
本研究旨在调查门控心脏扫描参数的变化,以诊断心脏手术候选患者。
在这项描述性横断面研究中,纳入40名心脏手术候选患者,以评估门控心脏扫描参数与心脏缺血面积之间的关系。对患者进行扫描后,检查并分析这些患者的TID、ESV、LHR、EF以及心脏壁的运动情况。
根据单样本t检验结果显示参数之间存在显著差异,结果在正常范围内(P值<0.0001)。此外,所有患者的心输出量和心脏壁运动问题均有变化。
心肌灌注扫描(MPS)和门控心脏扫描参数的评估可为诊断可能需要心脏手术的患者提供一种有效的方法。
