The first major section covers congenital heart disease (CHD), including its definition, epidemiology (0.8% of population born with CHD, 40% resolve spontaneously), etiology, classification into cyanotic and acyanotic types, common defects (VSD, ASD, PDA, Fallot's Tetralogy), clinical presentation (cyanosis types, digital clubbing, complications like infective endocarditis), and when to suspect CHD in a patient.
The next section addresses coronary artery disease (CAD), starting with its definition as the most common cause of death in developed countries. It covers risk factors (modifiable and non-modifiable), classification of acute coronary syndrome (STEMI, NSTEMI, unstable angina), clinical features of anginal pain (typical vs atypical), and management of stable angina including lifestyle modification, medications, and revascularization.
A dedicated section on dental management in ischemic heart disease provides specific protocols: timing rules post-MI (6-month safety period), medication adjustments for antiplatelets/anticoagulants (warfarin, aspirin, clopidogrel), local hemostatic measures, anesthesia cautions (max 3 ml of 2% lignocaine with adrenaline), and management of patients with cardiac pacemakers or history of stroke.
The hypertension section defines arterial hypertension (diastolic >90 or systolic >140 mmHg), classifies BP levels from optimal to grade 3, and lists etiologies (primary essential vs secondary causes like renal, endocrine, vascular). It covers clinical subtypes (white coat, masked, pseudohypertension), target organ damage (heart, brain, kidney, eyes), lifestyle management, and detailed dental management protocols including BP thresholds for elective vs emergency care and drug interactions.
