________ percent of patients enrolled in cardiac rehabilitation
programs have been reported to have hypertension
Forty-eight
Hypertensive heart disease can lead to
left
ventricular hypertrophy, LV systolic dysfunction,
atherosclerotic coronary artery disease, aortic
aneurysm and dissection, and sudden death.
Reportedly 95% of adults with high blood pressure
have what type of hypertension?
primary or essential hypertension. The cause of
primary hypertension is not completely understood,
but is due to a combination of genetic and
environmental factors, often with coexistent disease.
Elderly people often have
isolated or predominantly systolic
hypertension, which is due to stiffening of the aorta
with increasing age.
Name three common diseases which contribute to the
development and worsening of hypertension
obesity, sleep apnea, and intrinsic renal disease
What affects blood pressure
cardiac output and vascular resistance
Sodium retention
leads to a sequence of increased
fluid retention,
increased intravascular volumes, increased cardiac
output, and consequently raised blood pressures
Peripheral vascular resistance
is determined by
neurohormonal factors which act at the level of
arterioles
What medications are particularly effective in hypertensive patients
with tachycardia, and their hypotensive potency is
enhanced by co-administration with a diuretic
β blockers
β blockers lower blood pressure
by decreasing cardiac
output, due to a reduction in heart rate and
contractility.
Name some possible adverse affects of β blockers
associated with the worsening of
preexisting asthma and COPD, worsen hyperglycemia and dyslipidemia, cold feet, vivid dreams, and rebound
hypertension on discontinuation of drug
