I was just diagnosed with enlarged heart. (markedly dilate delft atrium). will keeping my bp in check keep me alive for many years? i'm 42.

Complex question : First is finding out why do you have a dilated left atrium. Do you have any mitral valve disease? Any history of atrial fibrillation? How is the left ventricular function at the 2d echocardiogram? Any systolic or diastolic dysfunction ? Without known why you have a dilated left atrim it's very difficult to predict future outcomes.
