DES most commonly refers to a **drug-eluting stent** used in cardiology. It is a small metal mesh tube placed inside an artery to help keep it open. DES is most often used during **percutaneous coronary intervention (PCI)** for coronary artery disease.

A Drug-Eluting Stent is a tiny metal mesh tube placed inside an artery to help keep it open. It slowly releases a medication into the vessel wall to reduce tissue re-growth inside the stent. It is most commonly used during coronary angioplasty for narrowed heart arteries. It can also be used in selected non-coronary arteries, depending on the condition and device.

A Coronary Stent is a small metal mesh tube placed inside a coronary artery. It helps keep an artery open after it has been widened with a balloon. It is most commonly used during a catheter-based procedure called percutaneous coronary intervention (PCI). It is used to improve blood flow to heart muscle when an artery is narrowed or blocked.

Balloon Angioplasty is a catheter-based procedure used to widen a narrowed or blocked blood vessel. It works by inflating a small balloon inside the vessel to improve blood flow. It is most commonly used in the heart’s coronary arteries and in peripheral arteries in the legs. It is often performed with imaging guidance in a cardiac catheterization or endovascular suite.

Angioplasty is a catheter-based procedure used to open narrowed or blocked blood vessels. It most commonly treats artery narrowing from atherosclerosis (plaque buildup). It is widely used in coronary arteries (heart arteries) and in peripheral arteries (legs, arms, kidneys). It may be performed with a balloon alone or combined with a stent (a small metal scaffold).

PCI stands for percutaneous coronary intervention. It is a catheter-based procedure used to open narrowed or blocked coronary arteries. PCI is most commonly performed in a cardiac catheterization laboratory (cath lab). It is used in both emergency care (heart attack) and planned care (stable coronary artery disease).

Percutaneous Coronary Intervention is a minimally invasive, catheter-based treatment to open narrowed or blocked coronary arteries. It is commonly performed in a cardiac catheterization laboratory using X-ray guidance and contrast dye. It often includes balloon angioplasty and frequently the placement of a coronary stent. It is used in both urgent heart attack care and planned treatment for stable coronary artery disease.

HbA1c is a blood test that reflects average blood glucose (sugar) levels over time. It measures how much glucose has attached to hemoglobin, the oxygen-carrying protein in red blood cells. HbA1c is commonly used to diagnose diabetes and to monitor long-term glucose control. In cardiovascular care, it is often used to understand cardiometabolic risk and guide overall risk assessment.

Hemoglobin A1c is a blood test that reflects average blood sugar (glucose) over time. It measures how much glucose is attached to hemoglobin, a protein inside red blood cells. It is commonly used to diagnose diabetes and to monitor diabetes control. Because diabetes strongly affects heart and blood vessel health, Hemoglobin A1c is frequently referenced in cardiovascular care.

A Coagulation Panel is a group of blood tests that assess how well your blood forms a clot. It helps clinicians understand bleeding risk and abnormal clotting risk in a broad way. It is commonly used in hospitals, emergency care, surgery planning, and cardiovascular clinics. It is also used to monitor or interpret the effects of certain blood-thinning medications.

Activated partial thromboplastin time (aPTT) is a blood test that measures how long it takes blood to clot. It helps assess part of the body’s clotting system, especially the “intrinsic” and “common” pathways. aPTT is commonly used in hospitals to monitor certain blood thinners and to evaluate unexplained bleeding or clotting. It is also used as a screening test before or during some cardiovascular procedures.

INR stands for *International Normalized Ratio*. It is a standardized way to report a blood-clotting test called the prothrombin time (PT). INR is most commonly used to monitor the effect of the blood thinner warfarin. It is also referenced when clinicians assess bleeding or clotting risk in certain illnesses.

eGFR means **estimated glomerular filtration rate**. It is a lab-reported number that **estimates how well the kidneys filter blood**. It is commonly calculated from a blood test such as **serum creatinine** (and sometimes cystatin C). Cardiologists use eGFR often because **kidney function strongly affects cardiovascular risk and treatment choices**.

Creatinine is a waste product made by muscles during normal energy use. It circulates in the blood and is removed mainly by the kidneys. Clinicians measure Creatinine in blood and urine to understand kidney function. In cardiovascular care, Creatinine helps guide testing and medication choices safely.

Sodium is a mineral and electrolyte that circulates in the blood and body fluids. It helps control fluid balance, blood pressure, and nerve and muscle function, including the heart. Sodium is commonly discussed in nutrition (salt in foods) and in medicine (blood tests and IV fluids). In cardiovascular care, Sodium levels and Sodium intake can influence symptoms and clinical decisions.

Magnesium is a mineral that also acts as an electrolyte in the body. It helps cells make energy and helps nerves and muscles function normally. In cardiovascular care, it is commonly discussed as a blood test value and as a treatment given by mouth or intravenously. It is also a key nutrient obtained from food and, in some cases, supplements.

Potassium is a mineral and electrolyte that helps cells work normally. It carries an electrical charge and is essential for nerve and muscle function, including the heart. In cardiovascular care, Potassium is commonly measured in blood tests and monitored during treatment. It is also discussed when clinicians adjust diet, fluids, and medications that affect heart rhythm.

Electrolytes are minerals in body fluids that carry an electrical charge. They help the heart beat regularly, keep blood pressure stable, and support normal muscle and nerve function. In cardiovascular care, Electrolytes are commonly checked with blood tests and interpreted alongside an ECG (electrocardiogram). They are also discussed when clinicians choose IV fluids, diuretics, or other medicines that affect fluid and salt balance.

hs-CRP is a blood test that measures very low levels of C-reactive protein (CRP). CRP is a protein made by the liver when inflammation is present somewhere in the body. The “hs” stands for high-sensitivity, meaning the assay can detect small CRP changes. It is commonly used in cardiovascular care to refine risk assessment for atherosclerotic disease.

C-reactive Protein is a blood protein that rises when the body has inflammation. It is made mainly by the liver in response to immune signals. Clinicians use it as a general marker of inflammation, not as a diagnosis by itself. In cardiovascular care, it is commonly used to support evaluation of inflammatory heart conditions and to help refine vascular risk discussion in selected people.
