Hypertension and Cardiovascular Disease
Hypertension and Cardiovascular Disease
Hypertension is a major risk factor for heart attacks and strokes, contributing to 40% of cases.
Direct-Acting Vasodilators in Hypertension
Direct-Acting Vasodilators in Hypertension
Direct-acting smooth muscle relaxants like hydralazine and minoxidil are not typically used as primary treatments for hypertension. Minoxidil, however, is used topically to stimulate hair growth in alopecia.
What is Angina Pectoris?
What is Angina Pectoris?
Angina pectoris is chest pain caused by reduced blood flow and oxygen supply to the heart. The more severe the oxygen deprivation, the more intense the pain.

Study Notes
Cardiovascular System
- The cardiovascular system (CVS) includes the heart, arteries, arterioles, veins, venules, and capillaries.
- The heart is a four-chambered pump (two atria, two ventricles).
- Common cardiovascular diseases include hypertension, hyperlipidemia (atherosclerosis), angina pectoris (chest pain), congestive heart failure (CHF), myocardial infarction (coronary heart disease), and arrhythmia (irregular heartbeat).
- Other cardiovascular diseases include congenital and rheumatic heart disease, and stroke.
Risk Factors of Cardiovascular Diseases
- Risk factors for cardiovascular diseases include hypertension, hyperlipidemia, diabetes, obesity, high dietary salt intake, alcohol consumption, cigarette smoking, insufficient physical activity, and stress.
Blood Pressure
- Blood pressure is the force of blood pushing against artery walls.
- Normal systolic blood pressure is below 120 mmHg, and diastolic blood pressure is below 80 mmHg.
- Systolic blood pressure is the pressure when the heart pumps blood.
- Diastolic blood pressure is the pressure when the heart is at rest.
Hypertension
- Hypertension is defined as sustained systolic blood pressure above 140 mmHg or sustained diastolic blood pressure above 90 mmHg.
- Hypertension results from increased peripheral vascular arteriolar smooth muscle tone.
Antihypertensive Agents
- Diuretics: Thiazide, loop, and potassium-sparing diuretics.
- Adrenergic agents: Beta-blockers (propranolol, atenolol, metoprolol), alpha-blockers (prazosin, doxazosin, terazosin).
- Angiotensin-converting enzyme (ACE) inhibitors: Enalapril, captopril, lisinopril. Side effect: dry cough and angioedema.
- Angiotensin II receptor blockers (ARBs): Losartan, candesartan, irbesartan. Side effect: less dry cough and angioedema.
- Calcium channel blockers: Verapamil, diltiazem, amlodipine, nifedipine. Side effect: leg edema.
- Central sympatholytics: Clonidine, methyldopa. Used in pregnant patients.
- Selective renin inhibitor: Aliskiren. Side effects: diarrhea, dry cough, and angioedema (especially at higher doses).
- Vasodilators: Hydralazine, minoxidil. Not typically used as primary hypertension treatment but can be used to stimulate hair growth topically.
Nursing Considerations for Hypertension
- High blood pressure increases the risk of ischemic heart disease and stroke. (40% attributed to HTN)
- Nurses need to accurately measure blood pressure using proper technique and equipment.
- Lifestyle changes (diet, exercise, stress reduction) are important.
- Ongoing monitoring and management of anti-hypertensive treatment are crucial.
Angina Pectoris
- Ischemia (decreased blood and oxygen supply) causes angina pectoris.
- Nitroglycerin (sublingual tablets) relaxes blood vessels to relieve pain.
- Nitroglycerin packs should be checked for expiry.
- Stable angina is worsened by exertion, unstable angina occurs at rest.
