Drug therapy for hypertension and the different antihypertensive treatment.
Full Answer Section
- Calcium channel blockers:Relax blood vessels by preventing calcium from entering smooth muscle cells in the vessel walls.
- Beta-blockers:Slow heart rate and decrease the force of heart contractions, reducing blood pressure.
- Vasodilators:Directly relax blood vessels.
- Severity of hypertension
- Presence of other medical conditions
- Side effects
- Types of Arrhythmias and Treatment
- Bradycardia:Slow heart rate (below 60 bpm). Treatment might involve medications or a pacemaker to increase heart rate.
- Tachycardia:Fast heart rate (above 100 bpm). Treatment might involve medications, lifestyle changes (e.g., avoiding stimulants), or procedures like ablation (destroying a small area of heart tissue causing the arrhythmia).
- Premature beats:Extra heartbeats that disrupt the normal rhythm. Treatment might involve medications or lifestyle changes.
- Atrial fibrillation (AFib):Irregular and often rapid heart rhythm. Discussed in detail below.
- Ventricular fibrillation (VFib):Chaotic heart rhythm that disrupts blood flow and can be life-threatening. Requires immediate medical attention (defibrillation).
- Atrial Fibrillation (AFib)
- Rate control medications:Slow down the heart rate to improve symptoms.
- Rhythm control medications:Attempt to restore normal heart rhythm.
- Anticoagulants (blood thinners):Reduce the risk of blood clots.
- Catheter ablation:A minimally invasive procedure to destroy small areas of heart tissue causing AFib.
- Types of Anemia
- Iron deficiency anemia:Most common type, caused by iron deficiency. Treated with iron supplements and addressing the underlying cause (e.g., blood loss).
- Vitamin deficiency anemia:Caused by deficiencies in vitamin B12 or folate. Treated with dietary changes or supplements.
- Aplastic anemia:Bone marrow doesn't produce enough red blood cells. Treatment may involve medications, blood transfusions, or stem cell transplant.
- Sickle cell anemia:Inherited genetic condition affecting red blood cell shape. Treatment focuses on managing symptoms and preventing complications.
- Thalassemia:Another inherited condition affecting hemoglobin production. Treatment varies depending on the severity.
Sample Answer
1. Hypertension Drug Therapy
Goals:
- Lower blood pressure (BP) to a target range set by guidelines (usually <130/85 mmHg for most adults).
- Reduce the risk of complications like heart attack, stroke, heart failure, and kidney disease.
Antihypertensive Treatments:
There are several classes of medications used to treat hypertension, each with its own mechanism of action:
- Diuretics: Increase urine output to decrease blood volume.
- Angiotensin-converting enzyme (ACE) inhibitors: Relax blood vessels by blocking a hormone that constricts them.
- Angiotensin II receptor blockers (ARBs): Block the action of a hormone that constricts blood vessels.
