Key Terms[edit]
Diagnosis[edit]
- Angina
A condition marked by severe pain in the chest, often also spreading to the shoulders, arms, and neck, caused by an inadequate blood supply to the heart.
- Atherosclerotic Coronary Artery Disease
(Also known as: Atherosclerosis, arteriosclerosis, coronary heart disease, hardening of the arteries) Coronary artery disease (CAD) is a condition which affects the arteries that supply the heart with blood. It is usually caused by atherosclerosis which is a buildup of plaque inside the artery walls.
- Cerebrovascular Accident
Cerebrovascular accident (CVA) is the medical term for a stroke. A stroke is when blood flow to a part of your brain is stopped either by a blockage or the rupture of a blood vessel. There are important signs of a stroke that you should be aware of and watch out for.
- Cerebrovascular Disease
Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. ... Narrowed cerebral arteries can lead to ischemic stroke, but continually elevated blood pressure can also cause tearing of vessels, leading to a hemorrhagic stroke.
- Chronic Kidney Disease
Chronic kidney disease (CKD) means your kidneys are damaged and can't filter blood the way they should. The main risk factors for developing kidney disease are diabetes, high blood pressure, heart disease, and a family history of kidney failure.
- Diastolic Heart Failure
Diastolic heart failure means the lower left chamber of the heart (left ventricle) is not able to fill properly with blood during the diastolic phase, reducing the amount of blood pumped out to the body.
- Heart Disease
Cardiovascular disease generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke. Other heart conditions, such as those that affect your heart's muscle, valves or rhythm, also are considered forms of heart disease.
- Hypertension
High blood pressure (HBP or hypertension) is when your blood pressure, the force of your blood pushing against the walls of your blood vessels, is consistently too high.
- Hypertensive Crisis
A hypertensive crisis is a severe increase in blood pressure that can lead to a stroke. Extremely high blood pressure — a top number (systolic pressure) of 180 millimeters of mercury (mm Hg) or higher or a bottom number (diastolic pressure) of 120 mm Hg or higher — can damage blood vessels.
- Myocardial Infarction
Also known as a heart attack which is a sudden and sometimes fatal occurrence of coronary thrombosis, typically resulting in the death of part of a heart muscle.
- Pulmonary Hypertension
Pulmonary hypertension is a life-threatening condition that gets worse over time, but treatments can help symptoms. Having pulmonary arterial hypertension (PAH) means that you have high blood pressure in the arteries that go from your heart to your lungs.
- Retinopathy
Hypertensive retinopathy is retinal vascular damage caused by hypertension. Signs usually develop late in the disease. Funduscopic examination shows arteriolar constriction, arteriovenous nicking, vascular wall changes, flame-shaped hemorrhages, cotton-wool spots, yellow hard exudates, and optic disk edema.
- Systolic Heart Disease
Heart failure with reduced ejection fraction (HFrEF), also called systolic failure: The left ventricle loses its ability to contract normally. The heart can't pump with enough force to push enough blood into circulation. ... The heart can't properly fill with blood during the resting period between each beat.
Procedures[edit]
9 Common Heart Surgeries: From Minimally Invasive to Transplant [14]
- Transmyocardial Laser Revascularization (TMR) – This procedure is usually performed to treat angina when no other treatments work. A small incision is done in the chest to expose the heart muscle, and a high-energy laser is used to make one millimeter wide channels inside the heart. The outer areas of the channels are closed, but the inner ones remain open to improve blood flow. It isn’t fully understood how TMR works, but there is evidence this surgery helps the heart grow tiny new blood vessels, which relieve angina.3
- Heart Valve Repair or Replacement – In most cases, this is an open heart operation. The surgeon opens the chest and heart to remove a damaged valve and a prosthetic one is sewn into place. There are some cases where the valve can be replaced through a small incision near the breastbone, making the surgery a minimally invasive one.4
- Heart Transplant – This type of surgery removes the patient’s diseased heart and replaces it with a healthy heart from a deceased donor. This operation is for patients who have end-stage heart failure, or for people whose heart is very damaged and weak.5
- Arrhythmia Treatment – Although many arrhythmias are harmless, some can be serious and even life threatening. An abnormal heart rate may not pump enough blood to the body, and it may damage the brain and other organs in the body. Some arrhythmias are treated with a pacemaker – a small device that gets placed under the skin of your chest. This device sends electrical pulses to help the heart beat at a normal rate. Another way to treat arrhythmias is an implantable cardioverter defibrillator (ICD). This device is also placed under the skin of your chest and uses electrical pulses to control arrhythmias. The ICD monitors the heart continuously, if it senses a dangerous arrhythmia, it sends an electric shock to the heart to restore it.6
- Aneurysm Repair – An aneurysm is a bulging or an out-pouching portion of a blood vessel. It can occur anywhere in the body, but it is particularly dangerous if it occurs in the aorta. This may happen when the artery wall weakens, and the blood moving through the artery makes the weak area An aneurysm can burst and cause fatal bleeding inside the body, hence repair surgery is performed prophylactically. The dilated part of the vessel gets removed and replaced with a graft, or synthetic material that won’t break.7
- Angioplasty – This minimally invasive procedure is used to widen narrowed or obstructed arteries or veins. A deflated balloon is attached to a catheter, passed over a guide-wire into the narrow vessel, and then inflated to a fixed size. Sometimes, a stent is inserted to make sure the vessel remains open, then the balloon gets deflated and removed.8
- Cardiomyoplasty – This surgical procedure takes healthy muscle from another part of the body, usually the latissimus dorsi from the patient’s back; and then it gets wrapped around the heart to provide support. A special pacemaker is also inserted to make the skeletal muscle contract.9
- Minimally Invasive Heart Surgery – Is performed to do some bypass, heart valve replacement, insert pacemakers, or use another vein or artery from the body to use it as a graft. As it name suggests, the chest is not cut open, but rather small incisions are made in the right side of the chest, and the surgeon operates between the ribs. The patient experiences less pain and quicker recovery, while it also gives the surgeon a better view of some portions of the heart versus an open-heart surgery.
