What cardiovascular manifestations are associated with adrenal insufficiency?

Low blood pressure and arrhythmias are the cardiovascular manifestations commonly associated with adrenal insufficiency. Adrenal insufficiency, particularly in cases like Addison's disease or secondary adrenal insufficiency, leads to a deficiency in cortisol and, in some cases, aldosterone. The lack of cortisol can result in reduced cardiac output and peripheral vascular resistance, leading to hypotension or low blood pressure.

Additionally, the deficiency of aldosterone can disrupt the electrolyte balance, specifically sodium and potassium levels. This imbalance can contribute to arrhythmias, as abnormal levels of these electrolytes can affect the heart's electrical conduction system. Thus, the combination of low blood pressure and the potential for arrhythmias makes this response accurate in the context of adrenal insufficiency.
