Heart Care For you

Endomyocardial Biopsy is a procedure that removes tiny samples of heart muscle for laboratory analysis. It is an invasive diagnostic test performed in a cardiac catheterization setting. It is most often encountered in heart transplant care and in selected cases of suspected myocarditis or infiltrative cardiomyopathy. Its main purpose is to provide tissue-level confirmation when imaging and blood tests are not enough.

Cardiac Sarcoidosis is an inflammatory condition where sarcoidosis involves the heart muscle and electrical system. It is a **disease/condition**, not a single symptom or test. It is commonly encountered in cardiology when evaluating unexplained arrhythmias, conduction disease, or cardiomyopathy. It also comes up when patients with known systemic sarcoidosis develop cardiac symptoms or abnormal cardiac testing.

Cardiac Amyloidosis is a condition where misfolded proteins deposit in the heart muscle. It is a form of infiltrative cardiomyopathy that can cause heart failure and arrhythmias. It is commonly encountered when evaluating unexplained thickened heart walls or “heart failure with preserved ejection fraction” (HFpEF). It is also considered when cardiac symptoms occur alongside systemic findings such as neuropathy or abnormal blood proteins.

Inherited Cardiomyopathy is a group of heart muscle conditions caused, at least in part, by genetic variants passed through families. It is a medical condition (not a symptom or a test) that changes how the myocardium (heart muscle) is built or how it functions. It is commonly encountered in cardiology clinics, heart failure care, sports cardiology, and inherited arrhythmia or genetics services. It often comes up when evaluating unexplained heart failure, thickened heart muscle, arrhythmias, or a family history of sudden cardiac death.

Cardiac Genetics is the study and clinical application of how inherited and de novo genetic variants influence heart and blood vessel disease. It is a clinical and laboratory discipline, not a single disease, and it often includes genetic testing and family-based risk assessment. It is commonly encountered in cardiology when evaluating cardiomyopathies, inherited arrhythmia syndromes, familial hypercholesterolemia, and heritable aortopathies. It helps connect a patient’s phenotype (observable features) to an underlying molecular cause and to implications for relatives.

MINOCA stands for **myocardial infarction with non-obstructive coronary arteries**. It is a **clinical syndrome (working diagnosis)** that looks like a heart attack but lacks a major coronary blockage on angiography. MINOCA is commonly encountered in **acute coronary syndrome** pathways in emergency and inpatient cardiology. It prompts clinicians to look for **alternative coronary and non-coronary mechanisms** of myocardial (heart muscle) injury.

Spontaneous Coronary Artery Dissection is a condition where a tear or bleeding occurs within the wall of a coronary artery. It can reduce blood flow to the heart muscle and cause an acute coronary syndrome (ACS). It is commonly encountered in emergency cardiology when evaluating chest pain and heart attack presentations. It is distinct from the more typical heart attack mechanism related to atherosclerotic plaque rupture.

Microvascular Angina is a clinical condition that causes angina-like chest discomfort from dysfunction in the heart’s small coronary vessels. It belongs to the category of ischemic heart disease syndromes, often discussed within “angina with non-obstructive coronary arteries.” It is commonly encountered when patients have typical angina symptoms but coronary angiography does not show major epicardial artery blockages. It is a key topic in chest pain evaluation, coronary physiology, and ischemia without classic obstructive coronary artery disease.

Coronary Spasm is a transient tightening of a coronary artery that reduces blood flow to the heart muscle. It is a clinical condition involving coronary vascular tone and myocardial ischemia. It is commonly encountered in the evaluation of chest pain, especially when coronary angiography shows little or no fixed blockage. It sits at the intersection of ischemic heart disease, vascular physiology, and arrhythmia risk assessment.

Myocardial Hibernation is a condition in which heart muscle is alive but contracts weakly because it receives chronically reduced blood flow. It is a concept within ischemic heart disease and heart failure (HF) evaluation, not a symptom by itself. It is commonly encountered when assessing left ventricular (LV) dysfunction in coronary artery disease (CAD). It matters because some dysfunction may improve if blood flow is restored.
