CH. 16 (EXAM #1) ADV
Identify three common cardiovascular diseases and explain the
pathophysiology associated with each disease.
Coronary heart disease is having plaque withing the coronary arteries which
can lead to the narrowing of these arteries and a decrease of blood flow to
these heart muscle fibers. Cardiac output is reduced and increases the
chance of having a heart attack (Powers et al. 413). Hypertension is having a
high blood pressure systolically over 130 or diastolic over 80, having this can
increase the likelihood of developing/having coronary heart disease, heart
failure, stroke, loss of vision, dementia (Powers et al. 415). Stroke is a rapid
onset of vascular induced brain dysfunction lasting longer than 24 hours. This
can be a result of prolonged ischemia and the person can be impacted
cognitively and have unilateral muscular weakness of upper and lower
extremities (Powers et al. 417).




Outline the benefits of cardiac rehab for patients with coronary heart disease.
Explain the mechanisms behind the exercise induced protection against
adverse health events.
Reduces the risk of adverse health events and lowering the risk factors
associated with CHD (Magyari 6). The mechanisms help to maintain a healthy
% of body fat, improve VO2 max, lower blood pressure, improve lipid blood
profile, and exercise induced cardio protections (Magyari 7).




Define hypertension and explain why hypertension poses numerous health
risks for hypertensive patients.
Hypertension- a defined elevation in systolic or diastolic blood pressure
(Powers et al. 415). It can increase the risk for atherosclerosis/CHD, heart
failure, stroke, loss of vision, and dementia (Powers et al. 415).

, Discuss the impact of both aerobic exercise and resistance exercise on blood
pressure in hypertensive individuals.
Aerobic training can reduce the systolic blood pressure by 5-8 mmHg,
resistance training may be able to lower blood pressure in these patients but
is an inferior treatment compared to aerobic training (Powers et al. 415-416).




Identify three mechanisms by which exercise training reduces blood pressure
in people with hypertension.
Exercise training increases the levels of nitric oxide in the blood vessels,
exercise reduces the rate of plaque formation in the blood vessels, and
aerobic exercise promotes the formation of new blood vessels (Powers et al.
416).




How does a stroke impacts cognitive function and motor function in patients?
The patients are impacted by unilateral muscle weakness of upper and lower
extremities and 33% experience a language disorder, aphasia (Powers et al.
417).




List and briefly discuss eight benefits of aerobic exercise for stroke patients.
Enhanced cardiorespiratory fitness, improved walking ability and motor
coordination, better balance, increased muscle force production, improved
cognitive ability, better postural control, reduced risks of future strokes, and
preconditioning of brain to resist future damage from strokes (Powers et al.
417).
