Study Notes
Overview of Hypertension
- Hypertension (HT) is a chronic disease with varying severity and progression among patients.
- Often asymptomatic in stages I and II, signs of HT emerge late, indicating extensive end-organ damage.
Risk of Untreated Hypertension
- Untreated HT leads to damage in blood vessels, heart, and kidneys, increasing the risk of significant health complications.
- Atherosclerosis accelerated by HT can result in strokes and heart disease such as myocardial infarction and heart failure.
Comorbidities and Complications
- Over 11 million Americans experience both hypertension and type 2 diabetes, which elevates risks for serious conditions like strokes and renal issues.
- Maintaining blood pressure in the normotensive range is critical when both HT and diabetes coexist.
Importance of Treatment
- Effective BP management can slow down the progression of vascular and cardiac lesions, reducing morbidity and mortality.
- Essential hypertension is often referred to as "The Silent Killer" due to its asymptomatic nature, which complicates treatment adherence.
Prevalence and Impact
- Hypertension is the most common cardiovascular condition, affecting approximately 50-60 million people in the U.S.
- A global estimate indicates that one billion people have hypertension; prevalent mostly in developing countries.
Treatment Outcomes
- A modest reduction in BP (4-6 mmHg) over several years can significantly lower stroke risk (42%), heart attack risk (16%), and total vascular mortality (21%).
Medication Compliance Issues
- Awareness is low, with nearly 30% of individuals unaware of their hypertension; inadequate treatment affects 27% of those diagnosed.
- Education regarding disease consequences is vital for improving adherence to prescribed antihypertensive therapy and lifestyle changes.
Blood Pressure Guidelines
- Blood pressure categories are defined as:
- Normal: <120/80 mmHg
- Elevated: 120-129/<80 mmHg
- Stage 1: 130-139/80-89 mmHg
- Stage 2: ≥140/≥90 mmHg
- Medication may be prescribed for Stage 1 if accompanied by cardiovascular risks or comorbidities.
Measurement Techniques
- BP should be measured in multiple positions (supine, standing, sitting) and arms during initial assessments to ensure accuracy.
- Automated BP monitoring devices aid in detecting hypertensive crises and assessing medication effectiveness.
Types of Hypertension
- Essential (Primary) Hypertension comprises 90% of cases; secondary hypertension arises from other medical conditions like renal disease or drug effects.
Drug-Induced Hypertension
- Medications that may elevate BP include:
- Alpha1-agonists, high-dose steroids, NSAIDs, stimulants, and certain antidepressants.
- Birth control pills can increase BP due to angiotensinogen synthesis.
Non-Pharmacological Treatment
- Lifestyle modifications such as reducing salt intake, managing weight, and addressing sedentary habits are essential in managing hypertension.
- Modifiable risk factors include stress, obesity, glucose intolerance, and alcohol consumption, while non-modifiable factors encompass age, gender, and family history.
