概括
升高的泛免疫炎症值 (PIV) 与非ST升高心肌梗塞 (NSTEMI) 患者心室节律失常的风险较高有关. 这种可访问的生物标志物可以改善风险评估和患者监测.
科学领域:
- 心脏病学 心脏病学
- 生物标志物 生物标志物
- 炎症 炎症是一种炎症.
背景情况:
- 系统性炎症在急性冠状动脉综合征中的作用是已知的,但其对NSTEMI相关心室节律失常的具体影响尚不清楚.
- 全免疫-炎症值 (PIV) 是一种来自常规血液计数的新型复合生物标志物,反映了免疫和血栓活性.
研究的目的:
- 调查全免疫炎症值 (PIV) 与患有NSTEMI的患者持续腹动脉/腹肌 (VT/VF) 的风险之间的关联.
主要方法:
- 一项回顾性队列研究分析了1788名接受皮肤冠状动脉干预的NSTEMI患者.
- 使用特定公式计算PIV: (中性粒细胞 × 血小板 × 单细胞) / 淋巴细胞.
- 统计分析包括后勤回归,ROC分析,卡普兰-梅尔曲线和受限立方斜线建模.
主要成果:
- 静脉动脉/静脉动 (VT/VF) 发生在1.9%的患者中,这些患者的PIV值明显更高.
- 多变量分析证实PIV是VT/VF的独立预测因子 (OR:每1000单位增加1.356).
- 较高的PIV四分位数与逐渐增加的VT/VF风险有关,并且PIV在添加到传统预测因素时改善了风险分类.
结论:
- 升高的PIV独立地与NSTEMI中的恶性心室节律失常有关.
- PIV 作为早期心律失常风险分层的一个可访问的生物标志物.
- PIV可以帮助指导NSTEMI患者的临床监测策略.

Myocarditis II: Clinical Features and Diagnostic Tests
267
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
540
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Psychoneuroimmunology: Cardiovascular Disease
402
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Acute Coronary Syndrome III: Diagnostic Studies
215
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...

Myocarditis IV: Nursing Management
207
Myocarditis is an inflammatory condition of the myocardium requiring meticulous nursing management for optimal patient outcomes. Effective management begins with a thorough assessment of the patient's medical history, paying close attention to past infections, autoimmune disorders, travel history, and exposure to toxins or drugs. Recent viral infections and systemic diseases are particularly relevant due to their potential role in triggering myocarditis.Physical Examination and MonitoringThe...
