概括

在心脏病发作后需要临时机械循环支持的非西班牙裔黑人患者面临更高的中风,损伤和死亡风险. 然而,他们经历的机械并发症较少,突出了急性心肌梗塞的具体种族差异.

科学领域:

心脏病学
健康差异研究
医疗技术的成果

背景情况:

对于急性心肌梗塞 (AMI) 后需要暂时机械循环支持 (tMCS) 的患者,结果的种族差异尚不清楚.
调查这些差异对于公平的患者护理至关重要.

研究的目的:

评估非西班牙裔黑人 (NHB) 与非西班牙裔白人 (NHW) 患者在AMI后需要tMCS的结果中的种族差异.
确定影响NHB患者的特定不良事件.

主要方法:

利用TriNetX美国协作网络 (2009-2023) 识别需要tMCS的NHB和NHW成年人.
员工倾向分数匹配 (PSM) 控制人口和临床变量.
评估的主要结局 (出血,缺血性中风) 和次要结局 (死亡率,心脏骤停,心脏衰竭等) 在多个时间点.

主要成果:

在90天和1年内,NHB患者的缺血性中风风险显著增加.
在所有随访期间,NHB患者的急性损伤率较高.
在NHB患者1年后,观察到全因死亡,心脏骤停和心室动的风险增加.

结论:

与NHW患者相比,接受tMCS后的NHB患者面临较高的缺血性中风,心血管事件和AKI风险.
出血的风险相似,但NHB患者发生AMI的机械并发症较少.
这些发现强调了AMI后的tMCS结果的显著种族差异,需要有针对性的干预措施.

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...
