Study Notes
Systemic Arterial Hypertension
- Defined as systolic blood pressure (SBP) > 130 mmHg or diastolic blood pressure (DBP) > 80 mmHg, confirmed on two separate office visits.
- Classification differs between adults and children, using percentile-based values for children.
Pathogenesis of Primary Hypertension
- Involves the interplay of genetic and environmental factors.
- Contributing mechanisms include genetic predisposition, increased sympathetic nervous system activity, overactive renin-angiotensin-aldosterone system (RAAS), endothelial dysfunction, and vascular remodeling.
- Results in increased blood volume and/or peripheral resistance, leading to an imbalance between cardiac output and peripheral vascular resistance.
Secondary Hypertension
- Caused by underlying diseases.
- Major categories: medications (oral contraceptives, NSAIDs, etc.), illicit drug use (cocaine, methamphetamines), primary kidney disease, primary aldosteronism (HTN, unexplained hypokalemia and metabolic alkalosis), renovascular hypertension, pheochromocytoma, Cushing syndrome, hyperthyroidism/hyperparathyroidism, coarctation of the aorta.
- Identification focuses on the presence of unusual onset (before age 30 or abrupt), severe HTN, or resistant HTN.
Risk Factors for Essential Hypertension
- Family history, African American ethnicity, high salt intake, alcohol consumption, obesity, and low physical activity.
Clinical Findings and Diagnostic Tests for Systemic Arterial Hypertension
- Symptoms of target organ damage: headaches, transient weakness or blindness, loss of visual acuity, chest pain, dyspnea, and claudication.
- Hypertensive retinopathy may indicate chronically elevated BP.
- Cardiac findings: laterally displaced PMI in LVH (left ventricular hypertrophy) and S4 heart sound.
- Diagnostic tests include blood tests (electrolytes, serum creatinine, urinalysis, fasting glucose and lipid panel), ECG (for LVH or ischemic changes), and echocardiography (for cardiac function assessment).
Systemic Arterial Hypertension: End-Organ Complications
- Common complications include heart disease (left ventricular hypertrophy, heart failure, myocardial infarction), kidney disease (chronic kidney disease, hypertensive nephrosclerosis), stroke (ischemic or hemorrhagic), and transient ischemic attack (TIA).
- Cardiovascular, renal, brain, and eye complications are detected and managed through clinical examination and diagnostic testing.
Main Diagnostic Strategies for Systemic Arterial Hypertension
- Clinical history, physical examination (blood pressure measurement, general presentation), laboratory tests, urinalysis, and imaging (e.g. ECG, CXR, echocardiogram).
Resistant Hypertension
- Hypertension that persists despite treatment with at least 3 antihypertensive medications.
- Often caused by secondary causes like renal artery stenosis, endocrine disorders, or drug interactions.
Vasculitis
- Inflammation of blood vessels.
- Classified by vessel size (small, medium, large).
- Underlying causes include dysfunctional inflammatory mechanisms, immune complex deposition, and direct vessel wall invasion.
Dyslipidemia
- Defined as abnormal lipid levels (high LDL, low HDL, high triglycerides) in the blood.
- Categories include primary (genetic) and secondary (lifestyle, diabetes, liver disease, medications) causes.
- Clinical features can be asymptomatic.
- Tests include fasting lipid panel and risk assessment using risk calculators .
Atherosclerosis
- Build-up of plaque in arteries.
- Pathophysiologic mechanisms include endothelial dysfunction (induced by hypertension, smoking, diabetes) leading to plaque formation, which narrows arteries.
- Common locations include coronary, carotid, and peripheral arteries.
- Leads to ischemia and downstream consequences for affected organs.
Leg Claudication
- Pain, fatigue, or cramping in the legs during exercise, relieved by rest, indicating vascular disease.
- Causes include peripheral arterial disease (PAD), venous claudication, and neurogenic claudication.
- Diagnosis aided by physical examination (pulses, bruits), ankle-brachial index (ABI), and optionally, imaging (e.g., Doppler ultrasonography, CT angiography).
Chest Pain
- Aetiology is multifactorial; clinical assessment uses an anatomic approach.
- Significant causes include myocardial infarction, pulmonary embolism, aortic dissection, and pericarditis.
- Diagnosis often involves electrocardiogram (ECG), cardiac biomarkers (troponin), and imaging (e.g., chest X-ray, cardiac catheterization).
Aortic Aneurysm
- Abnormal dilation of the aorta.
- Can be asymptomatic or present with pulsatile mass, back pain, or radiating/sudden chest pain.
- Commonly caused by atherosclerosis, hypertension, and cystic medial degeneration.
- Diagnosis often involves imaging (e.g., ultrasound, CT, MRI).
Aortic Dissection
- Splitting of the aorta's layers.
- Can lead to sudden, severe chest or back pain.
- Underlying causes include hypertension, connective tissue disorders, and trauma.
- Diagnosis requires urgent imaging (e.g., CT angiography).
Medication Nonadherence
- Failure to follow a prescribed medication regimen.
- Factors include patient-specific, social, and economic issues.
- Adherence is evaluated through clinical evaluation, patient questioning, and if appropriate, pill counts or adherence monitors.
SPIKES Framework (for delivering bad news)
- Preparation, Perception, Invitation, Knowledge, Empathy, Strategy, and Summary.
Xanthomas
- Yellowish, raised lesions in the skin due to deposition of lipid.
- Commonly caused by hyperlipidemia.
