Lipoprotein(a) is a cholesterol-carrying particle found in the blood. It is similar to LDL (“bad cholesterol”) but has an extra attached protein. Clinicians use it mainly as a cardiovascular risk marker. It is most commonly discussed in heart and vascular prevention visits and lipid (cholesterol) evaluations.

Lp(a) is a type of cholesterol-carrying particle found in the blood. It is similar to LDL (“bad cholesterol”) but has an additional protein attached. Clinicians most often use Lp(a) as a cardiovascular risk marker. It is discussed in heart and vascular prevention visits and in lipid (cholesterol) evaluations.

Apolipoprotein B is a protein found on certain cholesterol-carrying particles in the blood. It is commonly measured with a blood test to help assess cardiovascular risk. In simple terms, it helps estimate how many “atherogenic” (plaque-forming) lipoprotein particles are circulating. Clinicians often discuss it alongside standard cholesterol results such as LDL-C and non-HDL-C.

A Lipid Panel is a blood test that measures several fats (lipids) that circulate in the bloodstream. It is commonly used to assess cholesterol and triglycerides, which are linked to atherosclerosis (plaque buildup in arteries). Clinicians use it in primary care and cardiovascular medicine to estimate risk and to track response to prevention strategies.

D-dimer is a blood test marker that reflects recent blood clot formation and breakdown. It measures a protein fragment released when a clot dissolves in the body. Clinicians commonly use D-dimer when evaluating possible blood clots in the veins or lungs. It is also used in selected cardiovascular emergencies and hospital settings.

The NT-proBNP Test is a blood test that measures a heart-related hormone fragment called NT-proBNP. NT-proBNP levels often rise when the heart is under strain, especially from pressure or volume overload. It is commonly used in emergency and outpatient settings to evaluate symptoms such as shortness of breath and swelling.

The BNP Test is a blood test that measures brain natriuretic peptide (BNP), a hormone made mainly by the heart. BNP rises when the heart is under increased pressure or stretch, which can happen in heart failure. It is commonly used in emergency departments, hospitals, and cardiology clinics when patients have shortness of breath or fluid overload symptoms.

Creatine Kinase is an enzyme (a protein that helps chemical reactions happen) found mainly in heart and skeletal muscle. It helps muscles store and use energy during activity. In clinical care, Creatine Kinase is most commonly measured with a blood test to look for muscle injury. In cardiovascular medicine, it may appear in evaluations where heart muscle damage or significant muscle breakdown is being considered.

CK-MB is a laboratory measurement related to creatine kinase, an enzyme involved in cellular energy use. It is an “isoenzyme” (a specific form) that is found in higher concentrations in heart muscle compared with many other tissues. CK-MB is most commonly discussed in the evaluation of possible heart muscle injury, including heart attack (myocardial infarction). Today it is often used alongside, or in selected situations instead of, other cardiac blood tests such as troponin.

High-Sensitivity Troponin is a blood test that measures very small amounts of cardiac troponin. Cardiac troponin is a protein released when heart muscle cells are injured. High-Sensitivity Troponin is commonly used in emergency and hospital settings to evaluate possible heart attacks. It is also used to help assess risk and illness severity in some heart and non-heart conditions.

Troponin is a protein found inside heart muscle cells. It helps control how the heart muscle contracts. In medicine, Troponin most often refers to a blood test that looks for heart muscle injury. It is commonly used when clinicians evaluate chest pain or possible heart attack.

ABPM stands for ambulatory blood pressure monitoring. It is a way to measure blood pressure repeatedly over a full day and night while you go about usual activities. A small monitor connects to a blood pressure cuff worn on the upper arm. It is commonly used in cardiology and primary care to evaluate suspected or treated hypertension.

Ambulatory Blood Pressure Monitoring is a way to measure blood pressure repeatedly over a full day and night while you go about normal activities. A small monitor connects to an arm cuff and records readings automatically at set intervals. It is commonly used in cardiology and primary care to clarify whether blood pressure is truly high, low, or variable outside the clinic. It can also help evaluate nighttime blood pressure patterns that a single office reading cannot capture.

Blood Pressure Monitoring is the measurement of pressure inside the arteries as blood circulates. It is commonly done with an arm cuff in clinics, hospitals, and at home. It can also be measured continuously in selected hospital settings. The goal is to understand how blood pressure behaves over time, not just at one moment.

Vascular Ultrasound is an imaging test that uses sound waves to look at blood vessels and blood flow. It is commonly used to evaluate arteries and veins in the neck, abdomen, arms, and legs. It can help clinicians detect narrowing, blockage, clots, or abnormal flow patterns. It is usually performed in an outpatient clinic, hospital ultrasound lab, or vascular lab.

MRA most commonly means **magnetic resonance angiography**, a type of MRI focused on blood vessels. It creates pictures of arteries and veins to look for narrowing, blockages, bulges, or abnormal connections. MRA is commonly used in cardiology, vascular medicine, neurology, and radiology. In some cardiology contexts, “MRA” can also mean **mineralocorticoid receptor antagonist** (a heart failure medication class), but this article focuses on **magnetic resonance angiography**.

MR Angiography is a type of MRI scan that focuses on blood vessels. It creates detailed pictures of arteries (and sometimes veins) without using X-rays. It is commonly used to evaluate blood flow and vessel anatomy in the heart, chest, brain/neck, abdomen, and legs. Clinicians use it to help identify narrowing, blockages, aneurysms, and other vascular conditions.

CTA stands for computed tomography angiography. It is a CT scan technique that creates detailed pictures of blood vessels using X-rays and an injected contrast dye. CTA is commonly used to evaluate arteries and veins in the heart, chest, brain, abdomen, and legs. In cardiovascular care, it is often used to look for narrowing, blockages, aneurysms, or tears in blood vessels.

CT Angiography is a CT scan designed to show blood vessels after contrast dye is injected into a vein. It creates detailed pictures of arteries and veins throughout the body, including the heart and major vessels. Clinicians use it to look for narrowing, blockage, aneurysm, or abnormal vessel anatomy. It is commonly used in emergency and outpatient cardiovascular evaluation.

PVR most commonly means **pulmonary valve replacement**. It is a treatment that replaces a diseased or leaky **pulmonary valve**, which sits between the right ventricle and the pulmonary artery. PVR is often used in people with **congenital heart disease** (heart conditions present from birth). It can be done with **surgery** or with a **catheter-based** (minimally invasive) approach in selected patients.
