Triglycerides are a type of lipid (fat) made of glycerol plus three fatty acids. They are both a circulating biomarker measured on a lipid panel and a stored energy source in adipose (fat) tissue. In cardiology, Triglycerides are commonly encountered during cardiovascular risk assessment and metabolic evaluation. They are discussed alongside cholesterol fractions (low-density lipoprotein cholesterol and high-density lipoprotein cholesterol) in dyslipidemia.

HDL stands for high-density lipoprotein. It is a blood lipid particle and a laboratory measurement commonly reported on a lipid panel. HDL is often discussed in cardiology as part of cardiovascular risk assessment and prevention. It is sometimes called “HDL cholesterol,” although the cholesterol is carried within HDL particles.

LDL is low-density lipoprotein, a blood particle that carries cholesterol. LDL is a laboratory-related concept commonly discussed in lipid testing and cardiovascular risk assessment. LDL is encountered in cardiology when evaluating atherosclerotic cardiovascular disease risk and prevention strategies. LDL is often discussed alongside lifestyle changes and lipid-lowering medications in outpatient and inpatient care.

Hypercholesterolemia means a higher-than-desired level of cholesterol in the blood. It is a medical condition and a cardiovascular risk factor rather than a symptom. It is commonly identified on a lipid panel ordered in primary care and cardiology. In cardiology, it is closely linked to atherosclerotic cardiovascular disease risk assessment and prevention.

Hyperlipidemia is a condition in which levels of blood lipids are higher than expected. It is a metabolic and cardiovascular risk condition, not a symptom. It is commonly identified on a lipid panel during routine screening or cardiovascular risk assessment. In cardiology, it is discussed frequently because it contributes to atherosclerotic cardiovascular disease.

Pulmonary Hypertension is a cardiovascular condition in which pressure in the pulmonary arteries is abnormally elevated. It is a hemodynamic diagnosis that reflects disease affecting the pulmonary circulation and/or the left side of the heart. It is commonly encountered in cardiology during evaluation of unexplained dyspnea, right heart dysfunction, or abnormal echocardiography findings. It often overlaps with pulmonary medicine, critical care, and rheumatology because causes can be cardiac, lung-related, thromboembolic, or systemic.

Orthostatic Hypotension is a condition where blood pressure falls when a person moves to an upright posture. It is commonly discussed as a clinical sign and a physiologic problem rather than a single disease. It is often encountered in cardiology clinics, emergency care, and inpatient wards during syncope and dizziness evaluations. It sits at the intersection of cardiovascular hemodynamics and autonomic (involuntary nervous system) regulation.

Hypotension means blood pressure that is lower than expected for a person’s baseline and clinical situation. It is primarily a **clinical sign** (and sometimes a **syndrome** when paired with poor organ perfusion). It is commonly encountered in cardiology in settings like shock, heart failure, arrhythmias, and medication effects. It can be benign in some people and life-threatening in others, depending on context.

Hypertension is a condition where arterial blood pressure is persistently elevated above guideline-defined ranges. It is a chronic cardiovascular risk factor rather than a single symptom. It is commonly encountered in outpatient cardiology, primary care, emergency settings, and inpatient medicine. It often coexists with other cardiometabolic conditions and influences most cardiac risk assessments.

Blood Pressure is the force of circulating blood against the walls of the arteries. It is a vital sign and physiologic measurement used as a bedside “test” of cardiovascular status. It is commonly encountered in cardiology clinics, emergency care, inpatient wards, and perioperative settings. It helps clinicians interpret symptoms, estimate risk, and guide cardiovascular evaluation.
