We compared the expression of Са-ATPase (SERCA2a), calsequestrin (CASQ2), ryanodine receptors (RyR2) proteins and their genes (ATP2A2, CASQ2, and RYR2) in coronary heart disease (CHD) patients with and without comorbid type 2 diabetes mellitus. All studies were performed on the right atrial appendages resected during coronary bypass surgeries. Expression of SERCA2a and RyR2 proteins and their ATP2A2 (p=0.

In uniform cohort of patients, this expression differed significantly but positively correlated with the size of the left atrium, end-systolic volume, and end-diastolic volume. In contrast, SERCA2a expression negatively correlated with early (peak E) and late (peak A) diastolic filling rates in left ventricle.

In Wistar rats, coronary artery was ligated and intramyocardial injection of 12 or 24 mg Alloplant biomaterial suspension was performed. Histological analysis was conducted on paraffin sections stained by Mallory.

Postinfarction cardiosclerosis was formed within 6 weeks after coronary artery occlusion. Diabetes mellitus developed within 6 weeks after intraperitoneal injection of streptozotocin (60 mg/kg).

Postinfarction cardiosclerosis formed 6 weeks after coronary artery occlusion. Diabetes mellitus was induced by intraperitoneal injection of streptozotocin (60 mg/kg).
