    Study Notes

    Cardiology Overview

    • Cardiovascular disease is a leading cause of global mortality
    • Includes hypertension, coronary artery disease, heart failure, congenital defects, and strokes

    Hypertension (HTN)

    • Hypertension is when blood pressure, the force of blood pushing against blood vessels, is consistently too high
    • 2017 ACC/AHA criteria: persistent systolic blood pressure ≥ 130 mmHg and/or diastolic blood pressure ≥ 80 mmHg
    • Types: Primary (essential) and secondary hypertension
    • Causes: Genes, smoking, obesity, obstructive sleep apnea, heart defects, kidney disease, high salt intake, high alcohol consumption, stress, lack of exercise, aging, medication, and/or illegal drugs
    • Symptoms: Usually asymptomatic
    • Complications: Cardiac (CAD, HF), Aortic dissection, Central nervous system (intracranial hemorrhage, encephalopathy), kidneys (renal failure), and eyes (retinal changes)
    • Diagnosis: Need two readings, ideally 2 weeks apart. Quiet room, comfortable temperature, no smoking/coffee/exercise 30 minutes prior, empty bladder, relax for 3-5 minutes. Take 3 measurements at one-minute intervals, use average of last 2 readings
    • Management: Lifestyle modification (reduce salt intake, maintain healthy weight, eat enough potassium, eat balanced diet, be physically active, limit alcohol intake, don't smoke), pharmacological treatments, treating underlying causes if secondary.

    Coronary Artery Disease (CAD)

    • Condition where major blood vessels supplying the heart are narrowed (atherosclerosis)
    • Risk factors: High blood pressure, high cholesterol, diabetes, smoking, overweight/obese, inactive lifestyle, family history of premature heart disease, high-fat poor diet
    • Types: Stable angina, unstable angina, myocardial infarction (MI)
    • Symptoms: Typically, retrosternal chest pain or pressure, dyspnea, dizziness, palpitations, restlessness, anxiety, and autonomic symptoms (diaphoresis, nausea, vomiting)
    • Diagnostics: ECG, cardiac enzymes (Troponin, CK-MB), cardiac stress test, cardiac catheterization
    • Management: Risk factor modification, medical therapy (Aspirin, lipid-lowering agents, β-blockers, CCBs, Nitrates), revascularization (percutaneous coronary intervention [PCI] or Coronary artery bypass graft [CABG]), dual antiplatelet therapy (Aspirin + P2Y12 inhibitor, like clopidogrel)
    • Dental care modifications: Prevent ischemia or infarction, minimize anxiety, multiple short appointments, excellent post-operative analgesics, ideally patients are treated in dental setting 30 days post MI,ideally BLS certified
    • Patients on blood thinners: Average patient - no need to discontinue, use local measures to control bleeding; High bleeding risk patient - any suggested modification to medication regimen prior to dental surgery should be done/consulted w/ physician
    • Patients with ICDs or pacemakers: Some electronic dental devices may cause interference. Newer devices are better shielded, piezoelectric scalers may be safer than magnetostrictive models, electrosurgery has highest potential of electromagnetic interference. Proper use/distance of equipment are critical

    Valvular Disease

    • Damage to heart valves can lead to heart disease
    • Types: Stenosis, regurgitation, mixed
    • Signs and symptoms: Heart murmur, shortness of breath, swelling in the legs, chest pain, fatigue, dizziness, syncope/pre-syncope
    • Diagnostics: History & physical examination, Echocardiography (Echo), cardiac MRI, cardiac cauterization
    • Management: Medical management vs. valve replacement (bioprosthetic vs. mechanical), mechanical valves require lifelong anticoagulation, replaced valves risk infection
    • Dental management considerations: Infective endocarditis (serious disease with high mortality rate), antibiotic prophylaxis in high-risk patients

    Congenital Heart Disease (CHD)

    • CHD occurs when a problem with the heart is present at birth
    • Can affect heart shape & function
    • Signs/Symptoms: Varies greatly

    Heart Failure (HF)

    • A clinical syndrome where the heart can't supply enough blood to meet the body's demands
    • Causes: Coronary artery disease, hypertension, diabetes mellitus, valvular heart disease, infiltrative diseases. cardiac arrhythmias, obesity, smoking, lung disease, drugs and alcohol abuse
    • Signs & Symptoms: Dyspnea, orthopnea, paroxysmal nocturnal dyspnea, lower limb edema, fatigue
    • Physical examination findings: S3 heart sound, lung crackles, laterally displaced apical heart beat, coolness & pallor of lower extremites, jugular venous distention, liver enlargement
    • Diagnostics: History & physical, chest radiographs, echocardiogram (Echo), B-type natriuretic peptide (BNP)
    • Management: Lifestyle modification, Medications (β-Blockers, ACE inhibitors, ARBs, aldosterone antagonists, Hydralazine/nitrates, diuretics), occasionally patients might require invasive therapies (defibrillators & pacemakers), advanced HF requires heart transplant
    • Dental management considerations: Patients with well-compensated HF - no special modifications required, patients with decompensated HF - need to inquire about patients' ability to be placed in the supine position, Prolonged dental procedures may increase demand on the heart; patients may experience iatrogenic orthostatic hypotension. Positioning patient slowly, sitting with feet flat on floor. If diuretics, bathroom use before treatment recommended

    Arrhythmias

    • Irregular heart rates (accelerated, slowed, or irregular) caused by abnormalities in the electrical impulses of the myocardium.
    • Normal heart rate: 60-100 bpm
    • Types: Tachyarrhythmias (heart rates > 100 bpm), Bradyarrhythmias (heart rates < 60 bpm)
    • Clinical presentation: Fatigue, dyspnea, palpitations, dizziness, syncope, angina
    • Diagnostics: Simple ECG
    • Management: Medications (beta blockers, calcium channel blockers, antiarrhythmic medications), anticoagulation, radiofrequency catheter ablation (in some cases), intraventricular pacer (in some cases)
    • Atrial fibrillation is a common sustained arrhythmia that increases with age, characterized by multiple foci in the atria firing continuously in a chaotic pattern.
      • Patients on blood thinners: Average patient requires no discontinuation. High bleeding risk needs modification to medication regimen consultation with the physician prior to dental surgery

    Heart Transplant

    • Major concern: Lifelong use of immunosuppressants
    • Complications/Precautions: Watch for oral complications or side effects from medications (e.g., oral candidiasis, Cyclosporine-induced gingival hyperplasia) and anticoagulation needs
