How uncontrolled high blood pressure affect the left side of the heart?

Uncontrolled high blood pressure, or hypertension, forces the left side of the heart to work harder to pump blood against the elevated pressure in the arteries. This increased workload can lead to left ventricular hypertrophy, where the heart muscle thickens and becomes less efficient. Over time, this can result in heart failure, as the heart struggles to maintain adequate blood flow to the body. Additionally, it may increase the risk of arrhythmias and other cardiovascular complications.
