Study Notes

Overview of Cardiology

Cardiovascular disease is a leading global cause of mortality, encompassing conditions like hypertension, coronary artery disease, heart failure, congenital defects, and strokes.

Hypertension (HTN)

Defined by persistent systolic BP ≥ 130 mm Hg or diastolic BP ≥ 80 mm Hg.
Types include primary hypertension (idiopathic) and secondary hypertension (due to underlying conditions).
Symptoms are often absent; complications include coronary artery disease (CAD), heart failure, strokes, renal failure, and retinal changes.
Diagnosis requires two elevated BP readings, ideally spaced two weeks apart.
Management involves lifestyle changes and medications, with common drugs including beta blockers, diuretics, ACE inhibitors, ARBs, and calcium channel blockers.
Dental practice modifications depend on BP levels, e.g., no modifications if BP < 160/100 mm Hg; referrals for patients with persistent elevated BP.

Coronary Artery Disease (CAD)

Characterized by narrowing of coronary arteries due to atherosclerosis.
Symptomatology includes retrosternal chest pain, dyspnea, dizziness, and autonomic symptoms.
Diagnostics involve ECG, cardiac enzymes, stress tests, and catheterization.
Management focuses on risk factor modification, medical therapy (e.g., Aspirin), and potential revascularization treatments such as PCI or CABG.
Anxiety management during dental treatments is crucial to prevent ischemia; patients post-MI can be safely treated after 30 days.

Valvular Heart Disease

Involves four heart valves; conditions may include stenosis, regurgitation, or mixed lesions.
Symptoms vary but may include heart murmur, dyspnea, edema, and fatigue.
Diagnosed via physical exams, echocardiograms, and cardiac MRI.
Treatment options include medical management and valve replacement, with lifetime anticoagulation required for mechanical valves.
Infective endocarditis risk highlighted for certain patients, necessitating antibiotic prophylaxis based on specific criteria.

Congenital Heart Disease

Congenital heart disease presents at birth, potentially affecting heart shape and function, leading to significant health concerns.

Heart Failure (HF)

Clinically defined as the heart's inability to meet the body's blood supply needs, caused by CAD, hypertension, and other factors.
Common symptoms include dyspnea, orthopnea, and lower limb edema; physical examination may reveal specific heart sounds and distension indicators.
Diagnostics include history, echocardiograms, and BNP tests.
Management combines lifestyle modifications and medications, with advanced cases requiring heart transplant.
Special dental considerations for HF patients involve evaluating supine positioning and managing orthostatic hypotension.

Arrhythmias

Defined as abnormal heart rates: bradyarrhythmias (<60 bpm) and tachyarrhythmias (>100 bpm).
Common types include atrial fibrillation, ventricular tachycardia, and other supraventricular rhythms.
Presenting symptoms often include fatigue, palpitations, and dizziness; diagnosis typically via ECG.
Management includes medications (beta blockers, antiarrhythmics) and potential invasive treatments for life-threatening arrhythmias.

Heart Transplant

Requires lifelong immunosuppressants; patients may also face anticoagulation.
Be attentive to oral complications from medications, such as candidiasis and gingival hyperplasia.

Dental Management Considerations

Understand the need for modifications in dental procedures based on cardiovascular conditions.
Antibiotic prophylaxis is critical for patients at risk for infective endocarditis.
Maintain awareness of drug interactions, particularly with anticoagulants during dental care.

Case Scenarios

Case scenarios involving dental treatment decisions based on patients' cardiovascular histories illustrate the application of guidelines and management strategies in clinical practice.
