KIN 462 Quiz 2 Trial

Which chronic CV condition is most consistent with this patients presentation?

Heart Failure with preserved ejection fraction

Which mechanism best explains the development of HFpEF in this patient with long-standing hypertension and left ventricular hypertrophy?

Increased afterload leading to the concentric hypertrophy and impaired ventricular compliance

T/F The patients history of MI significantly increases his risk of developing both systolic and diastolic forms of heart failure.

T

Given the patients age and symptoms, which additional health screening is advisable?

Echocardiographic monitoring and BNP measurement

In an elderly patient with a history of MI and HFpEF, which clinical scenario strongly suggests progression to systolic heart failure?

Progressive decline in EF <40% with increased LV dilation and reduced SV

Given his past MI, which symptoms should prompt immediate reevaluation of his cardiac status?

SOB

How does James chronic hypertension contribute to the development of left ventricular hypertrophy

Hypertension increases afterload, cause the LV to thicken and compensate for increased vascular resistance.

T/F LVH due to hypertension decreases myocardial O2 demand, reducing the risk of ischemia in patients with CAD

False

What role does oxidative stress play in the progression of James CAD

Promotes to LDL oxidization, which contributes to atherosclerotic plaque formation
