Insights

People living with HIV (PLHIV) and HIV-uninfected patients had similar long-term risks after acute coronary syndrome (ACS). However, PLHIV experienced more frequent ACS recurrence, highlighting a critical area for cardiovascular care improvement.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Public Health

Background:

  • Long-term prognosis after acute coronary syndrome (ACS) in people living with HIV (PLHIV) remains unclear.
  • Understanding cardiovascular outcomes in PLHIV is crucial for effective disease management and prevention strategies.

Purpose of the Study:

  • To compare major adverse cardiac and cerebrovascular events (MACCE) after a first ACS between PLHIV and HIV-uninfected (HIV-) patients.
  • To identify determinants of cardiovascular prognosis in these populations.

Main Methods:

  • A cohort study enrolled consecutive PLHIV and matched HIV- patients experiencing their first ACS across 23 coronary intensive care units in France.
  • Patients were matched for age, sex, and ACS type.
  • The primary endpoint was MACCE (cardiac death, recurrent ACS, recurrent coronary revascularization, stroke) assessed at 36-month follow-up.

Main Results:

  • No statistically significant difference in overall MACCE risk was observed between PLHIV (17.8%) and HIV- patients (15.1%) at 36 months (P=0.22).
  • Recurrent ACS was significantly more frequent among PLHIV (multivariable HR, 6.31; P=0.02), with HIV infection identified as the sole independent predictor.
  • PLHIV were less likely to quit smoking (47% vs. 75%; P=0.01) and showed smaller decreases in total cholesterol (-22.3 vs. -35.0 mg/dL; P=0.04).

Conclusions:

  • While overall long-term cardiovascular event risk was similar, PLHIV face a higher risk of recurrent ACS after an initial event.
  • HIV infection is an independent predictor of ACS recurrence.
  • Differences in lifestyle factors (smoking cessation) and lipid management may contribute to disparities in cardiovascular outcomes.

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

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...

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
