ARBs are angiotensin II receptor blockers, a class of prescription cardiovascular drugs. They lower blood pressure and reduce harmful neurohormonal signaling in the heart and vessels. They are commonly encountered in cardiology clinics, inpatient wards, and heart failure programs. They are often discussed alongside ACE inhibitors (angiotensin-converting enzyme inhibitors) and other renin–angiotensin–aldosterone system therapies.

ACE Inhibitors are medications that lower the activity of the renin–angiotensin–aldosterone system (RAAS). They are a drug class commonly used to treat high blood pressure and several forms of heart disease. They are frequently encountered in cardiology clinics, inpatient wards, and post–myocardial infarction care. They are also widely discussed in medical education because they connect cardiovascular physiology with kidney function.

Beta Blockers are medications that reduce the effects of adrenaline-like signals on the heart and blood vessels. They are a drug class used widely in cardiology and internal medicine. They are commonly encountered when treating arrhythmias, coronary artery disease, hypertension, and heart failure. They also appear frequently in exam questions because they connect physiology, pharmacology, and clinical decision-making.

Cardiac Biomarkers are laboratory tests that measure molecules released into blood when the heart is injured, stressed, or remodeling. They belong to the category of diagnostic tests (blood-based biomarkers). They are commonly encountered in emergency cardiology for chest pain and in inpatient/outpatient care for heart failure evaluation. They help clinicians connect symptoms to underlying cardiac physiology and disease mechanisms.

D Dimer is a blood test marker that reflects breakdown of a blood clot. It is a laboratory test, not a disease or a medication. It is commonly used when clinicians are assessing possible venous thromboembolism, including pulmonary embolism. In cardiology, it often appears in the evaluation of acute chest pain, shortness of breath, syncope, and suspected aortic syndromes.

CRP stands for C-reactive protein. CRP is a blood test marker that reflects inflammation somewhere in the body. CRP is a laboratory test (a biomarker), not a diagnosis by itself. In cardiology, CRP is commonly encountered in risk discussions about atherosclerosis and in inflammatory or infectious heart conditions.

NT proBNP is a blood test marker used in cardiology to assess cardiac stress. It is a laboratory test, not a disease or a symptom. It is commonly encountered when evaluating shortness of breath and suspected heart failure. It is also used for risk assessment and follow-up in several cardiovascular conditions.

BNP stands for B-type natriuretic peptide, a hormone made mainly by the heart. BNP is a laboratory test result and a biomarker used to assess cardiac stress. BNP is commonly encountered when evaluating shortness of breath and suspected heart failure. BNP is also used in cardiology to support risk assessment and follow-up discussions.

CK MB is a blood test marker that reflects injury to muscle cells, including heart muscle cells. CK MB stands for the MB isoenzyme of creatine kinase (CK), an enzyme involved in cellular energy transfer. It is a laboratory test used in the evaluation of suspected myocardial injury, especially in time-sensitive clinical settings. It is commonly discussed in cardiology alongside cardiac troponins and electrocardiography (ECG).

Troponin is a family of proteins involved in muscle contraction. In cardiology, Troponin most often refers to a blood test used to detect heart muscle injury. It is a laboratory biomarker (a test result), not a symptom or a diagnosis by itself. It is commonly encountered in emergency care and inpatient cardiology when chest pain or possible myocardial infarction is being evaluated.
