Blood Pressure – Low / High – Normal / Systolis / Diastolic

Definition of Blood Pressure Blood Pressure – the force blood exerts against the walls of the arteries as it travels through them, as a combination of resistance and the heart’s pumping effort. A sphygmomanometer is the device that measures blood pressure, reported in millimeters of mercury (mm Hg). A typical blood pressure reading reports the pressure at the […]

Coronary Artery Bypass Graft (CABG)

Definition of Coronary Artery Bypass Graft (CABG) Coronary Artery Bypass Graft (CABG) is a surgical operation to replace diseased coronary arteries supplying the heart with blood. Cardiovascular surgeons began performing CABG to treat severe coronary artery disease (cad), typically following heart attack, in the 1960s. The operation became feasible with refinements in cardiopulmonary bypass technology and surgical technique. In the […]

Homocysteine Definition and Heart Diesease

Definition of Homocysteine Homocysteine is an amino acid in the blood that the body’s metabolism of the essential amino acid methionine produces. (An essential amino acid is one the body cannot synthesize itself but must obtain from dietary sources.) B vitamins and folic acid are necessary to break down homocysteine. Accumulation of homocysteine in the blood […]

Radiofrequency Ablation – Procedure

Definition of Radiofrequency Ablation Procedure A therapeutic procedure to treat arrhythmia disorders such as wolff parkinson-white syndrome or paroxysmal atrial tachycardia (pat). Radiofrequency ablation uses high-frequency energy, similar to microwave energy, to destroy abnormal electrical pathways in the heart. The cardiologist performs radiofrequency ablation via cardiac catheterization, threading a catheter through a blood vessel and into the heart. Electrodes on the […]

Aging, Cardiovascular Changes That Occur With

Cardiovascular Changes With Advancing Age The most significant age-related changes in cardiovascular function occur at birth in both sexes and with menopause in women. Though changes in metabolism occur with aging that affect all body systems, researchers now believe cardiovascular health does not inherently decline simply as a function of aging. Diabetes, obesity, lack of physical exercise, […]

Body Shape and Cardiovascular Health

Infroduction Body shape and cardiovascular health – Although obesity in general raises the risk for numerous health conditions, the distribution pattern of excess body fat correlates to the level of risk for cardiovascular disease (cvd) as well as other health conditions such as diabetes. Numerous research studies affirm that people who carry excess body fat primarily around […]

DASH Eating Plan – Diet

What is DASH Eating Plan The acronym for “dietary approaches to stop hypertension.” The DASH eating plan is the result of a pair of clinical research studies and features a diet high in fruits, vegetables, low-fat dairy products, whole grain products, and low in fats (particularly saturated fats) and sodium. Numerous studies correlate dietary habits, particularly […]

Implantable Cardioverter Defibrillator (ICD)

Definition of Implantable Cardioverter Defibrillator (ICD) Implantable cardioverter defibrillator (ICD) is a small, battery-operated electronic device, similar to a pacemaker, that monitors the heart’s electrical activity for certain patterns of arrhythmia and administers a moderate electrical shock when the heart stays in the pattern beyond the programmed length of time. One or two wires, called leads, extend […]

Risk Factors For Cardiovascular Disease

Most Common Risk Factors For Cardiovascular Disease The circumstances that make a person more or less likely to develop conditions affecting the heart and cardiovascular system. A risk factor may be fixed, or immutable, such as age, ethnicity, or gender. Other risk factors are variable, or mutable. These are the risk factors that an individual can […]

Angiogram – Procedure and Risks

Definition of Angiogram Test Angiogram is a diagnostic test to visualize blood vessels. The test is an angiography; the result is an angiogram. The cardiologist or vascular specialist injects dye into the relevant blood vessels to assess the flow of blood through them, observing the flow via fluoroscopy (moving X-rays). Angiography is useful for diagnosing peripheral vascular […]
