What condition is a client with increased cardiac workload from secondary hypertension at risk of developing?

A client with increased cardiac workload due to secondary hypertension is at risk of developing myocardial hypertrophy because the heart has to work harder to pump blood against elevated resistance in the arteries. This increased workload leads to changes in the heart muscle itself; the heart muscle cells can grow in size, resulting in hypertrophy. Over time, this can contribute to various cardiovascular issues, including heart failure, arrhythmias, and even ischemic heart disease due to decreased efficiency in the heart's ability to supply blood.

Increased venous tone, arterial lumen dilation, and hepatic damage are not primary concerns in the context of secondary hypertension and increased cardiac workload. While these conditions can occur due to other pathologies or stressors, they do not directly relate to the compensatory changes in the heart that arise from the increased demands placed by high blood pressure related to secondary hypertension. Understanding the connection between hypertension, cardiac workload, and myocardial adaptation is crucial in recognizing the risks associated with unmanaged high blood pressure.
