Study Notes

Hypertension

Pathophysiology: Involves endothelial cell activation leading to inflammation and impaired vasodilation.
Complications: Can lead to cardiovascular disorders and renal issues.
Risk Factors for Hypertension:
- Aging, particularly over 65 years
- Smoking and sedentary lifestyle
- Genetic predisposition affecting salt sensitivity
- Diet and excess alcohol intake
- Chronic conditions such as diabetes and hyperlipidemia
- Stress and gender factors

Manifestations

Earliest signs often go unnoticed; persistent symptoms can include headaches, dizziness, and fatigue.

Assessment/Management

Regular blood pressure monitoring
Lifestyle modifications and medication adherence are crucial for control.

Nonpharmacological Interventions

Encourage healthy diet rich in fruits and vegetables.
Promote regular physical activity.
Stress management techniques.

Pharmacological Interventions

Medication selection depends on the patient's age and coexisting conditions.
Adverse effects of medications:
- Watch for hyperkalemia with potassium-sparing diuretics.
- Dry cough as a common side effect of ACE inhibitors.
- Caution with vasodilators due to risk of orthostatic hypotension.

Hyperlipidemia

Serum lipid values are crucial for diagnosis and management.
Know normal values for total cholesterol and lipoproteins.

Angina Management & Myocardial Infarction

Immediate treatment is critical; "time is muscle".
Interventions for MI:
- PCI (Percutaneous Coronary Intervention) to open blocked arteries.
- CABG (Coronary Artery Bypass Graft) to improve blood flow to heart.

Heart Failure

Two types: Right-sided and Left-sided heart failure.
Etiology of Right-sided Heart Failure:
- Occurs when the right ventricle fails, leading to systemic fluid overload (e.g., edema, ascites).
Left-sided Heart Failure:
- Results in pulmonary congestion, causing symptoms like crackles and orthopnea.

Clinical Manifestations

Right-sided: jugular venous distention, peripheral edema, weight gain.
Left-sided: dyspnea, confusion, shallow respirations, nocturia.

Diagnostics

Chest X-ray to identify heart enlargement.
ECG for assessing severity and type of heart failure.
Brain Natriuretic Peptide (BNP) levels indicate ventricular pressure increase.

Treatment Options

Anticoagulants to reduce thromboembolism risk.
Diuretics to relieve fluid overload.
ACE inhibitors and beta-blockers for vasodilation and lowering blood pressure.
Positive inotropes like digoxin for improving heart contractility.

Nursing Interventions

Monitor for shortness of breath and volume overload.
Daily weight checks to assess fluid retention.
Patient education on symptom management and adherence to treatment.

Risk Factors for Heart Conditions

Include hypertension, coronary artery disease (CAD), history of myocardial infarction, older adults, and various comorbidities (e.g., diabetes, tobacco use).

Compensatory Mechanisms

Body attempts to maintain cardiac output and blood pressure through various physiological responses.

Management Strategies

Incorporate both lifestyle and medical therapies tailored to individual needs for optimal heart health.
