Study Notes
Overview of Hypertension
- Hypertension (HT) is primarily a chronic disease, often asymptomatic, especially in stage I and II.
- End-organ damage occurs late in the disease progression, affecting blood vessels, heart, and kidneys.
- Long-term treatment with blood pressure-lowering medications is typically essential.
- Lifestyle changes, including exercise, healthy diet, low salt intake, and stress reduction, are critical initial treatments and can sometimes negate the need for medications.
Consequences of Untreated Hypertension
- High BP damages blood vessels, leading to serious complications:
- Atherosclerosis accelerates, resulting in cerebral artery issues (transient ischemic attacks, strokes) and coronary artery diseases (angina, acute coronary syndromes).
- Chronic cardiac ischemia can cause heart failure.
- Renal artery atherosclerosis can lead to chronic kidney disease, necessitating dialysis or transplants.
- High blood pressure contributes to global health crises:
- 13.5% of premature deaths, 54% of strokes, and 47% of ischemic heart disease deaths worldwide are linked to high BP.
Treatment Gaps
- Almost 30% of individuals with hypertension are unaware of their condition.
- 14% of those diagnosed remain untreated, while 27% receive inadequate treatment.
- Only 26% achieve adequate treatment levels.
- Essential hypertension has an unknown cause but is costly both for patients and healthcare systems.
Blood Pressure Classification
- New guidelines categorize blood pressure as follows:
- Normal: <120/80 mmHg
- Elevated: 120-129 systolic and <80 diastolic
- Stage 1: 130-139 systolic or 80-89 diastolic
- Stage 2: ≥140 systolic or ≥90 diastolic
- Medication is advised for Stage I hypertension if there's a history of cardiovascular events or significant risk factors.
Comorbidity with Diabetes
- Over 11 million Americans have both hypertension and type 2 diabetes.
- Hypertension not only increases prevalence in diabetic patients but also elevates cardiovascular risks.
- Effective blood pressure management is crucial to slow vascular and cardiac lesion development and reduce morbidity and mortality.
Medication Compliance and Education
- Essential hypertension—dubbed "The Silent Killer"—is often asymptomatic, which can lead to poor compliance with antihypertensive therapies.
- Side effects of medications may deter treatment adherence.
- Patient education on the disease’s natural progression and effects is vital to improve compliance and encourage lifestyle changes.
Epidemiology and Impact
- Hypertension is the most prevalent cardiovascular condition, affecting approximately 50–60 million people in the U.S. and one billion globally.
- A reduction of 4-6 mmHg in BP over 3-5 years can significantly lower stroke risk by 42%, myocardial infarction risk by 16%, and total vascular mortality by 21%.
- Effective management of hypertension is essential to mitigate risks of strokes, heart attacks, and kidney disease.
