10 Questions
What is the primary cause of left ventricular congestive failure according to the text?
Pulmonary venous congestion
Which compensatory mechanism is described as related to end-diastolic volume (EDV) and helps normalize cardiac output?
Frank-Starling law
What can chronic pulmonary congestion potentially lead to, as mentioned in the text?
Right ventricular failure
Which pathophysiological mechanism of heart failure involves persistent arrhythmias?
Myocardial dysfunction
How does chamber dilation affect heart function according to the text?
Interferes with diastolic function
What type of hypertrophy is typically seen in response to systolic pressure overload?
Concentric hypertrophy
Which compensatory mechanism is activated in response to heart failure and leads to vasoconstriction?
Activation of the renin-angiotensin-aldosterone system (RAAS)
What effect does continued neuro-hormonal activation have on a failing heart?
Exacerbates congestive signs
Which of the following is NOT a consequence of worsening heart failure?
Decreased morbidity
What is a recommended treatment approach for heart failure according to the text?
Dietary salt reduction
Learn about heart failure, which occurs when abnormal cardiac function leads to inadequate blood delivery to the tissues. Discover how right ventricular congestive failure results in systemic venous hypertension and more, while left ventricular congestive failure leads to pulmonary venous congestion and edema.
