Cardiovascular disorders are among the most critical health concerns nurses face, significantly affecting patient outcomes and quality of life. A deep understanding of pathophysiology, symptomatology, diagnostic criteria, and management options is imperative for nurses, especially for NCLEX preparation and real-world clinical practice.
Heart Failure
Heart Failure is a complex, chronic condition characterized by the heart's reduced capability to pump sufficient blood to meet the body's metabolic demands. There are two main types of heart failure: Left-sided and Right-sided.
Left-sided Heart Failure
Left-sided heart failure typically leads to pulmonary congestion as blood accumulates in the lungs due to inadequate left ventricular function.
Symptoms include:
- Shortness of breath, especially upon exertion
- Persistent cough with white or pink blood-tinged sputum
- Fatigue
- Difficulty lying flat (orthopnea)
Right-sided Heart Failure
Right-sided heart failure is often a consequence of left-sided heart failure or pulmonary diseases, leading to peripheral edema and organ congestion.
Symptoms include:
- Peripheral edema (swelling in ankles and legs)
- Abdominal swelling due to fluid accumulation
- Weight gain from fluid retention
- Hepatomegaly (enlarged liver)
Diagnostic Procedures
- B-type natriuretic peptide (BNP) blood test
- Chest X-rays
- Echocardiograms
- Electrocardiogram (ECG)
- Cardiac MRI or CT scans
Management
- Lifestyle modifications: low-sodium diet, fluid restrictions
- Medications: ACE inhibitors, beta-blockers, diuretics, and angiotensin receptor blockers
- Surgical interventions: implantation of ventricular assist devices (VAD), heart transplants

Hypertension
Hypertension, also known as high blood pressure, is often called the 'silent killer' due to its asymptomatic nature. Persistent hypertension can lead to severe cardiovascular complications such as myocardial infarction, stroke, and kidney failure.
Risk Factors:
- Obesity
- Sedentary lifestyle
- Excessive salt intake
- Alcohol consumption
- Genetic predisposition
Diagnostic Criteria
- Elevated systolic blood pressure ≥130 mmHg
- Elevated diastolic blood pressure ≥80 mmHg
Management
- Lifestyle modifications: diet (DASH diet), regular exercise, weight management, smoking cessation
- Pharmacological treatment: diuretics, ACE inhibitors, beta-blockers, calcium channel blockers

Coronary Artery Disease (CAD)
Coronary Artery Disease involves the narrowing or blockage of coronary arteries due to plaque accumulation, significantly increasing the risk of heart attack and stroke.
Symptoms
- Angina (chest pain)
- Shortness of breath
- Fatigue
- Heart attack (myocardial infarction)
Diagnostic Procedures
- Stress tests (exercise tolerance test)
- Coronary angiography
- Advanced imaging: CT angiography
Management
- Lifestyle interventions: diet, physical activity, weight reduction
- Pharmacological treatment: statins, antiplatelet agents, beta-blockers
- Surgical interventions: angioplasty with stenting, coronary artery bypass grafting (CABG)

Arrhythmias
Arrhythmias encompass irregularities in the heart's electrical conduction system, potentially resulting in inefficient blood circulation and increased cardiovascular risk.
Types and Symptoms
- Bradycardia (slow heart rate)
- Tachycardia (fast heart rate)
- Atrial fibrillation
- Symptoms: dizziness, palpitations, fatigue, syncope
Diagnostic Procedures
- Electrocardiogram (ECG)
- Holter monitor (continuous ECG monitoring)
- Event monitors
Management
- Pharmacological therapy: beta-blockers, antiarrhythmics
- Procedures: cardioversion, catheter ablation
- Devices: pacemakers, implantable cardioverter-defibrillators (ICDs)

Peripheral Vascular Disease (PVD)
Peripheral Vascular Disease involves reduced circulation to peripheral body parts, especially the legs, due to vessel narrowing or blockage.
Symptoms
- Intermittent claudication (pain with walking)
- Numbness or tingling in legs
- Skin discoloration and ulcers
Diagnostic Procedures
- Ankle-brachial index (ABI)
- Doppler ultrasound
- Angiography
Management
- Lifestyle modifications
- Pharmacological therapy: antiplatelet agents, vasodilators
- Interventions: angioplasty, vascular surgery
