Insights

Resistance to activated protein C (APCR) was found in 30% of men who had myocardial infarction. This finding suggests APCR may play a role in arterial thrombosis and warrants further investigation for prevention strategies.

Area of Science:

  • Hematology
  • Cardiovascular Medicine
  • Genetics

Context:

  • Activated protein C resistance (APCR) is a common inherited coagulation disorder, primarily linked to venous thromboembolism.
  • The association between APCR and arterial thrombosis, particularly myocardial infarction, remains less understood.
  • This study investigates APCR prevalence in male myocardial infarction survivors without traditional cardiovascular risk factors.

Purpose:

  • To determine the prevalence of APCR in men who have experienced myocardial infarction.
  • To assess potential links between APCR and specific coagulation and lipid parameters in these patients.

Summary:

  • Thirty percent of male myocardial infarction patients (n=20) exhibited APCR, compared to none in the control group (n=20).
  • APCR patients showed elevated fibrinogen, LDL-C, APO B100, oxidized LDL antibodies, and C4 levels.
  • Positive correlations were found between the APCR ratio and fibrinogen/oxidized LDL antibodies.

Impact:

  • The high prevalence of APCR in this cohort suggests its potential significance in arterial thrombosis.
  • Findings support considering APCR screening for primary prevention of arterial thrombosis.
  • This research may inform secondary prevention strategies for thromboembolic complications.

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...

Myocarditis II: Clinical Features and Diagnostic Tests

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 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...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
Acute Coronary Syndrome I: Introduction01:30

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...
