Study Notes

Key Terms and Definitions

Anemia: Decreased red blood cells or hemoglobin in the body.
Angina Pectoris: Chest pain or discomfort due to coronary artery disease (CAD).
Anti-embolic Stockings: Special stockings worn to prevent blood clots and improve circulation.
Artery: Blood vessels carrying blood away from the heart.
Atria: Upper chambers of the heart (right and left atrium).
Capillaries: Small vessels facilitating gas, nutrient, and waste exchange between blood and cells.

Cardiovascular Conditions

Cardiomyopathy: Weakening of the heart muscle affecting blood pumping efficiency.
Congestive Heart Failure (CHF): Heart fails to pump effectively, failing to meet the body's activity needs.
Coronary Artery Disease (CAD): Damage and narrowing of coronary arteries leading to reduced blood supply to the heart.
Myocardial Ischemia: Insufficient blood supply to heart muscle, leading to cell death.
Pulmonary Edema: Accumulation of fluid in the lungs, typically from heart failure.

Heart Function and Phases

Diastole: Relaxation phase of the heart.
Systole: Contraction phase where blood is pumped out of the left ventricle.
Heart Structure: Composed of four chambers—two atria and two ventricles.

Blood Components and Functions

Blood: Transports oxygen, nutrients, hormones, salts, and antibodies; removes carbon dioxide and waste.
Platelets: Important for blood clotting to prevent excessive bleeding.
Erythrocytes, Leukocytes, Thrombocytes: Types of blood cells—red blood cells, white blood cells, and platelets, respectively.
Plasma: Liquid part of blood, primarily composed of water.

Respiratory and Circulatory Interactions

Oxygen and Carbon Dioxide Exchange: Occurs in the lungs; carbon dioxide is exhaled while oxygen is inhaled.

Cardiovascular Response to Aging

Heart pumps less efficiently, leading to narrowed and less elastic blood vessels, resulting in decreased blood flow.

Specific Conditions and Symptoms

Stable Angina: Chest pain during physical activity or stress.
Unstable Angina: Chest pain at rest or minimal exertion.
Left-Sided CHF Symptoms: Includes fatigue, orthopnea, coughing, rapid pulse, and weight gain.
Right-Sided CHF Symptoms: Includes fatigue, weakness, edema in extremities, bulging neck veins, and irregular heartbeat.

Vascular Diseases

Peripheral Vascular Disease (PVD): Insufficient blood circulation to extremities.
Peripheral Arterial Disease (PAD): Most common type of PVD.

Other Important Terms

Occlusion: Complete obstruction of a blood vessel.
Hypoxia: Insufficient oxygen supply to the body.
Prehypertension: Increased risk of developing high blood pressure in the future.
Nitroglycerin: Medication that relaxes coronary artery walls for improved blood flow.
