Flashcards

What is hypertension?

Hypertension, also known as high blood pressure, is a chronic condition where the force of blood against the artery walls is consistently elevated.

Why is hypertension a serious medical condition?

Hypertension is a major public health concern affecting millions globally, contributing to heart disease, stroke, and kidney failure.

How does untreated hypertension affect the body?

Untreated hypertension can damage various organs, including the heart, brain, kidneys, and eyes, potentially leading to life-threatening complications.

What factors contribute to blood pressure regulation?

Blood pressure is controlled by a complex interplay of resistance, capacitance, pump output, and volume.

What is resistance in blood pressure regulation?

Resistance, also known as peripheral vascular resistance, is the force opposing blood flow. It's primarily influenced by the diameter of blood vessels.

What is capacitance in blood pressure regulation?

Capacitance refers to the ability of blood vessels to expand and hold blood. It's affected by factors like elasticity and volume.

How does pump output impact blood pressure?

Pump output, referring to the heart's pumping action, influences blood pressure. Increased cardiac output raises blood pressure.

How does blood volume impact blood pressure?

Blood volume, the total amount of blood circulating in the body, affects blood pressure. Increased blood volume can lead to higher blood pressure.

How can lifestyle changes impact blood pressure?

Lifestyle changes, such as adopting a healthy diet, exercising regularly, and reducing stress, can significantly lower blood pressure.

What are antihypertensive medications?

Antihypertensive medications are drugs used to treat hypertension by lowering blood pressure.

How do sympathetic agents work in lowering blood pressure?

Sympathetic agents work by blocking the release or action of neurotransmitters like norepinephrine, leading to vasodilation and reduced heart rate.

How do calcium channel blockers affect blood pressure?

Calcium channel blockers decrease the influx of calcium into vascular smooth muscles, promoting relaxation and vasodilation.

How do beta-blockers reduce blood pressure?

Beta-blockers block the action of beta-adrenergic receptors in the heart and vascular system, reducing heart rate and blood pressure.

Signup and view all the flashcards

How do alpha-1 blockers affect blood pressure?

Alpha-1 blockers inhibit the action of alpha-1 receptors, leading to vasodilation and decreased blood pressure.

How do direct vasodilators work?

Direct vasodilators act directly on blood vessels, causing them to relax and expand, thus lowering blood pressure.

How do ACE inhibitors reduce blood pressure?

Angiotensin-converting enzyme (ACE) inhibitors block the enzyme ACE, preventing the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor.

How do ARBs affect blood pressure?

Angiotensin II receptor blockers (ARBs) block the action of angiotensin II by binding to its receptors, preventing vasoconstriction.

How does Aliskiren lower blood pressure?

Aliskiren inhibits renin, an enzyme involved in the production of angiotensin I, effectively reducing angiotensin II levels and lowering blood pressure.

How do diuretics lower blood pressure?

Diuretics increase urine production, leading to a decrease in blood volume and consequently lower blood pressure.
