I have lvh-moderate concentric, isvd 1.2, posterior wall 1.2. i have hypertension. how bad are heart measurements?

Not too bad: Some analyses of left ventricular hypertrophy use wall thickness, such as you provide, to estimate prognosis and others use calculated left ventricular mass. Hypertension is a common cause of this increase in wall thickness. But your measurements are near normal: 0.6 to 1.1 cm. You likely should be on angiotensin modifying drug(s) and, most importantly, keep you blood pressure under good control.
