概括
增长差异化因子15 (GDF-15) 在低风险急性胸痛患者中没有显著预测阻塞性冠状动脉疾病 (CAD) 或再血管化需求. 这些发现质疑GDF-15在该人群中预后的临床实用性.
科学领域:
- 心脏病学 心脏病学
- 生物标志物 生物标志物
- 诊断成像 诊断成像 诊断成像
背景情况:
- 生长差异化因子15 (GDF-15) 在组织损伤和压力时升高.
- 它对阻塞性冠状动脉疾病 (CAD) 和急性胸痛患者的复血管化的预测价值尚不清楚.
研究的目的:
- 评估GDF-15是否预测阻塞性CAD或需要在30天和12个月内进行再血管化.
- 评估GDF-15在患有急性胸痛的低/中等风险患者的预后效用.
主要方法:
- 537名住院患者的高灵敏度托罗邦素T (hs-cTnT) 低于99百分位,接受了冠状动脉CT血管造影 (CCTA).
- 使用后勤回归分析计算GDF-15 (日志转换) 预测结果的几率比率 (OR).
- 分析根据年龄,性别和临床共变量进行了调整.
主要成果:
- 在年龄/性别调整的分析中,GDF-15最初与阻塞性CAD和再血管化需求有关.
- 在对临床共变量进行调整后,GDF-15失去了作为预测因素的统计意义.
- 将hs-cTnT水平添加到模型中也使得GDF-15变得无关紧要.
结论:
- 在患有急性胸痛但没有急性心肌梗塞的患者中,GDF-15并没有显著改善阻塞性CAD或再血管化需求的识别.
- 在低风险急性胸痛患者的预后中,GDF-15的临床有用性值得怀疑.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
Acute Coronary Syndrome III: Diagnostic Studies
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
Angina III: Clinical Manifestations and Assessment
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...
