Insights

Chromogranin A (CgA) levels predict long-term mortality and heart failure hospitalizations in acute coronary syndromes (ACSs). This biomarker offers valuable prognostic information beyond traditional risk factors.

Area of Science:

  • Cardiology
  • Biomarkers
  • Prognostics

Background:

  • Acute coronary syndromes (ACSs) represent a spectrum of clinical presentations of myocardial infarction.
  • Accurate risk stratification is crucial for managing ACS patients and improving outcomes.
  • Conventional risk markers may not fully capture the complexity of patient prognosis.

Purpose of the Study:

  • To investigate the prognostic value of circulating chromogranin A (CgA) levels in patients with ACS.
  • To determine if CgA provides independent prognostic information beyond established cardiovascular risk factors.

Main Methods:

  • A cohort of 1268 ACS patients had their baseline CgA levels measured.
  • Patients were followed for a median of 92 months for mortality and clinical events.
  • Statistical analyses, including adjustments for conventional risk markers, were performed.

Main Results:

  • Elevated CgA levels were strongly associated with increased long-term mortality and heart failure hospitalizations.
  • The association between CgA and mortality remained significant after adjusting for conventional risk factors.
  • CgA also independently predicted heart failure hospitalizations, but not recurrent myocardial infarction or stroke.

Conclusions:

  • Circulating chromogranin A is an independent predictor of long-term mortality and heart failure hospitalizations in ACS patients.
  • CgA offers incremental prognostic value, enhancing risk prediction beyond traditional cardiovascular risk markers.

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...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

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...

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...

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...

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...
