A 73-year-old patient has increased pulmonary pressure resulting in right heart failure. What could be a potential cause for the right heart to fail?

Choice A rationale
Implementing a smoking cessation program, while beneficial for overall health and cardiovascular risk reduction, is not the primary therapeutic goal for secondary hypertension. Secondary hypertension is high blood pressure caused by an underlying condition. Therefore, the primary goal is to treat the underlying condition.
Choice B rationale
Treating the specific etiological disease is the primary therapeutic goal for secondary hypertension. By treating the underlying cause, blood pressure can often be lowered or returned to normal.
Choice C rationale
Initiating a rapid weight-loss program is not the primary therapeutic goal for secondary hypertension. While weight loss can help lower blood pressure in general, the primary goal in secondary hypertension is to treat the underlying cause.
Choice D rationale
Starting a rigorous exercise regimen, while beneficial for overall health and cardiovascular risk reduction, is not the primary therapeutic goal for secondary hypertension. The primary goal is to treat the underlying condition causing the high blood pressure.

Choice A rationale
Reducing the overall contractility of the heart muscle is not the primary reason for performing Coronary Artery Bypass Surgery (CABG)4. In fact, reducing the contractility of the heart muscle could potentially decrease the heart’s ability to pump blood effectively.
Choice B rationale
Reducing plaque buildup in the carotid artery is not the primary reason for performing CABG4. While plaque buildup in the carotid artery can lead to serious conditions such as stroke, CABG is specifically performed to bypass blocked coronary arteries, not carotid arteries.
Choice C rationale
Increasing the oxygen supply to the heart muscle is the primary reason for performing CABG4. When coronary arteries become blocked or narrowed due to plaque buildup, the heart muscle may not receive enough oxygen-rich blood. CABG is performed to create a new route, or bypass, around the blocked artery, which improves blood flow and oxygen supply to the heart muscle.
Choice D rationale
Increasing the myocardial workload is not the primary reason for performing CABG4. In fact, increasing the workload of the heart could potentially exacerbate heart disease and lead to complications such as heart failure.
