- Discuss challenges faced in the profession.
- Explore knowledge on cardiac risks, atherosclerosis, and myocardial infarction.
- Groups share discussion highlights on critical topics.
Heart Disease and Cardiac Biomarkers Overview
- The heart is vital for maintaining blood flow in the circulatory system with its four chambers: two atria and two ventricles.
- Arteries possess thick walls to accommodate blood volume, while veins have thinner walls and valves preventing backflow.
- Heart disease results from impaired cardiac pumping and fluid retention, potentially affecting heart layers (pericardium, myocardium, endocardium).
- Cardiac enzymes are indicators released during heart injury, crucial for diagnosing myocardial infarction but must be evaluated alongside clinical findings.
Role of Cardiac Biomarkers
- Cardiac biomarkers play a critical role in identifying myocardial damage due to ischemia and heart failure.
- Blocked blood flow and oxygen deprivation lead to myocyte injury and death, releasing biomarkers into the circulation.
- Two primary categories of cardiovascular diseases detectable through biomarkers:
- Acute ischemic disease, including AMI.
- Heart failure.
Characteristics of Optimal Cardiac Biomarkers
- Ideal cardiac markers should be:
- Specific to myocardial tissue.
- Present in low concentrations in healthy individuals.
- Released rapidly after myocardial injury.
- Persistent in circulation for sufficient diagnostic window.
