Study Notes

Overview

Cardiovascular disease is a primary global mortality cause.
Conditions include hypertension, coronary artery disease, heart failure, congenital defects, and strokes.

Hypertension (HTN)

Characterized by consistent high blood pressure: systolic ≥ 130 mmHg and/or diastolic ≥ 80 mmHg (2017 ACC/AHA).
Types: Primary (essential) and Secondary (due to underlying conditions).
Often asymptomatic, but complications include coronary artery disease, heart failure, aortic dissection, and strokes.
Diagnosis requires two readings, ideally two weeks apart.
Management strategies involve lifestyle changes and medications such as beta blockers, diuretics, ACE inhibitors, ARBs, and calcium channel blockers.
Dental considerations:
- Blood pressure < 160/100 mmHg: No modifications needed.
- Blood pressure > 160/100 mmHg: Treatment modifications may be required.

Coronary Artery Disease (CAD)

Caused by the narrowing of heart blood vessels often due to atherosclerosis.
Symptoms include retrosternal chest pain, dyspnea, dizziness, and anxiety.
Diagnostics include ECG, cardiac enzymes (Troponin), stress tests, and catheterization.
Management can include risk factor modification, medical therapy (e.g., Aspirin, β-blockers), and revascularization procedures (PCI or CABG).
Dental modifications are essential to prevent ischemia; multiple short appointments recommended.
Patients on blood thinners should usually continue their medications; consult with the physician for high-risk cases.

Valvular Disease

Involves four heart valves; damage leads to stenosis or regurgitation.
Symptoms: Heart murmur, dyspnea, leg swelling, chest pain, fatigue.
Diagnostics involve history, physical exams, echocardiogram, and cardiac catheterization.
Management and interventions may involve medications or valve replacement (bioprosthetic or mechanical).
Anticoagulation is necessary for mechanical valves; ensure antibiotic prophylaxis to prevent endocarditis for at-risk patients.

Congenital Heart Disease

Present at birth; can affect heart shape and function.
Requires careful dental management due to association with infective endocarditis.

Heart Failure (HF)

A clinical syndrome where the heart fails to supply adequate blood.
Common causes: CAD, hypertension, diabetes, and valvular disease.
Signs: dyspnea, orthopnea, edema, fatigue, and physical findings like S3 heart sound.
Diagnostics include chest radiographs and echocardiography.
Management involves lifestyle changes and medications (e.g., β-blockers, ACE inhibitors); may require heart transplants for advanced cases.
Patients with well-compensated HF typically don't need special dental modifications, while those decompensated require careful assessment.

Arrhythmias

Irregular heart rates due to abnormal electrical impulses; normal rates are between 60-100 bpm.
Types: Bradyarrhythmias (< 60 bpm) and Tachyarrhythmias (> 100 bpm).
Diagnosis typically made via ECG.
Treatment for tachyarrhythmias may include beta blockers or antiarrhythmics, while bradyarrhythmias may need pacemakers.
Atrial fibrillation is the most common sustained arrhythmia; requires lifelong anticoagulation due to stroke risk.

Heart Transplant

Lifelong immunosuppressant therapy is necessary to prevent organ rejection.
Patients may experience oral complications due to medications.

Dental Management Considerations

Considerations for patients with heart conditions include:
- Stress management to prevent increased heart rates.
- Adjustments for patients on anticoagulants, particularly before dental procedures.
- Precautions for devices like ICDs or pacemakers to avoid electromagnetic interference.

Case Scenarios

Case 1: For a patient with controlled hypertension (BP: 130/90 mmHg), proceed with elective dental care with no modifications needed.
Case 2: A patient with a history of aortic valve replacement requires antibiotic prophylaxis (e.g., amoxicillin) before procedures involving gingival manipulation.
