Diziness fatigue nausea stomach.

My mother who is 81 years ols suffered an heart attack in June 2020. She was put of following medicines since than under the supervison of cardiologist. Lipikind cv 10/75, Dytor plus 5 half, Razo 20, Metolar xr 12.5, Angiplat 2.5. She is for the past few months feeling dizziness, loss of appetite, fatigue in the morning only. By afternoon it is ok. Even loss of energy is there. Today nausea in stomach also. Today checked her bp in home with omron monitor. The reading fluctuated from 122/66 till 102/49, 112/57, 119/60 in a gap of one hour. Are the medication responsible. Lipid profile conducted in June has been normal. My question is whether statins decrease bp as mentioned here. Is vertigo responsible or omron electronic bp monitor has a problem .
