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.
