With the evaluation of focal epicardial coronary stenosis and non-obstructive atherosclerosis, the cardiac scans play a significant role in diagnosing coronary artery disease (CAD). Moreover, the advancements in the imaging techniques leading to improved risk assessment and timely therapies help in early diagnosis of CAD with greater accuracy.
To evaluate the role of cardiac scan in diagnosing CAD.
Recruited 100 individuals without any history of CAD that refers to the assessment of suspected angina, conducted the prospective study. Electrocardiogram (ECG) findings assisted in the evaluation of left bundle branch blockage, abnormalities of ST-segment, and pathological Q waves.
The results depicted negative N.M findings among 38 respondents; whereas, ischemia and myocardial infarctions were diagnosed in 26% and 19% of the respondents, respectively. The majority of the males (59) were positive in contrast to 37 females with positive results. Similarly, 24 respondents were presented with mild dilated left atria (LA), 37 respondents suffered from impaired relaxation pattern of left ventricular (LV) diastolic filling; while, 40 of the respondents had normal global LV systolic function.
The study results have concluded that non-invasive, low-risk, and cost-effective technique like ECG is an important beneficial advancement in the diagnosis of CAD.
通过评估局灶性心外膜冠状动脉狭窄和非阻塞性动脉粥样硬化，心脏扫描在诊断冠状动脉疾病（CAD）方面发挥着重要作用。此外，成像技术的进步带来了风险评估的改善和及时的治疗，有助于更准确地早期诊断 CAD。
评估心脏扫描在诊断 CAD 中的作用。
招募了 100 名没有 CAD 病史的个体，这些个体是为了评估疑似心绞痛的患者，进行了前瞻性研究。心电图（ECG）检查有助于评估左束支传导阻滞、ST 段异常和病理性 Q 波。
结果显示 38 名受访者的 N.M 检查结果为阴性；而 26%和 19%的受访者分别被诊断为缺血和心肌梗死。大多数男性（59 人）呈阳性，而女性呈阳性的则有 37 人。同样，24 名受访者有轻度扩张的左心房（LA），37 名受访者有左心室（LV）舒张充盈的松弛模式受损；而 40 名受访者的 LV 收缩功能正常。
研究结果表明，心电图等非侵入性、低风险和具有成本效益的技术是 CAD 诊断的重要有益进展。
