- 放射学 放射学是一门学科.
背景情况:
- 心肌梗塞 (MI) 患者缺乏标准可修改风险因子 (SMRF) 越来越被认可.
- 这些患者面临心血管不良事件的重大风险.
- 识别和治疗这一群体是一个临床挑战.
研究的目的:
- 在没有SMRF的MI患者中评估冠状动脉 (CAC) 评分升高的患病率.
- 确定这些患者中适用于预防性治疗的比例,如他类药物.
- 评估与SMRF状态和CAC分数有关的心血管结果.
主要方法:
- 对429名心脏病发作患者进行了计算机断层扫描CAC扫描 (2001-2021) 的回顾性分析.
- SMRF定义为高血压,高脂血症,糖尿病或吸烟.
- 主要终点:在没有SMRF的患者中,CAC升高 (>50%ile) 和他类药物指示 (CAC≥100AU或≥75%ile).
主要成果:
- 在429名心脏病发作患者中,有60人没有SMRF.
- 没有SMRF的患者表现出高的CAC流行率 (82% ≥ 50%ile;中位数80%ile).
- 77%的非SMRF患者满足了预防治疗的标准; CAC分数较低的结果更有利.
结论:
- 没有SMRF的MI患者表现出高的冠状动脉样硬化负担,由CAC得分表明.

01:20Imaging Studies for Cardiovascular System III: X-Ray
178
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

01:17Ischemic Heart Disease: Overview
1.3K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

01:20Blood Studies for Cardiovascular System I: Cardiac Biomarkers
141
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

01:17Imaging Studies for Cardiovascular System I:Echocardiography
318
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...
