HYPERTENSION & CLINICAL MANIFESTATIONS
- Hypertension is classified as primary and secondary. Primary hypertension is about 95% of the patient. The cause cannot be determined although probably results from environmental (e.g. lifestyle) and genetic factors. Secondary hypertension is caused by other disease, usually endocrine (e.g. Cushing syndrome)
- Hypertension is a silent killer because people who have it are often symptoms free. With prolonged high BP, it damages the blood vessels (endothelium). Inflammation in the endothelium causes atherosclerotic disease (dyslipidemia) which contribute to myocardial infarction (MI), cerebrovascular accident (CVA) and chron
GERONTOLOGIC CONSIDERATIONS
● Elevated in systolic blood pressure in isolation
- Decrease elasticity and the accumulation of atherosclerotic plaque in the major blood vessels - Volume expansion associated with structural and functional changes in the kidney - Changes in the strength of cardiac contraction
● Consider less rigid blood pressure control to target less than 150/90. Lower target may increased risk for orthostatic hypotension putting older adults at risk for falls and fractures.
● Be aware of finances and drug interactions among older adults, thus if appropriate consider a monotherapy for blood pressure control
Formula BP
BP = CO x PVR
SV x HR (1 minute)
Increase in blood pressure is related to increase in cardiac output (CO) and constriction of the blood vessels. Increase CO is associated with volume expansion.
ASSESSMENT & DIAGNOSTIC FINDINGS
● URINALYSIS & URINE TEST
- Presence of protein in the urine, particularly the amount of macroalbuminuria/microalbuminuria; 24 hours urine creatinine & protein
● BASIC METABOLIC PANEL (BMP) SODIUM CHLORIDE BUN GLUCOSE Diabetes Mellitus -CO2 POTASSIUM
CREATININE - Kidney Functions
ASSESSMENT & DIAGNOSTIC FINDINGS
● LIPID PROFILE
- High level cholesterol, low-density lipoprotein (LDL), Triglycerides / Low level high-density lipoprotein (HDL) contribute to myocardial infarction and stroke
● 12 LEAD ELECTROCARDIOGRAM (EKG)
- Provides information of the rhythm of the heart
● ECHOCARDIOGRAPHY
- Ultrasound of the heart that provides moving pictures and information of the structure and function of the heart (e.g. left ventricular hypertrophy)

● HYPERTENSIVE EMERGENCY
- Life-threatening blood pressure that requires immediate treatment to prevent target organ damage (e.g. myocardial infarction, intracranial hemorrhage)
- Use of intravenous vasodilators to gradually decrease blood pressure ●
HYPERTENSIVE URGENCY
- Blood pressure is very elevated but there is no evidence of target organ damage - Fast-acting antihypertensive oral medication is recommended for treatment
