Myocardial Pathological Changes in Patients of Type 2 Diabetes With or Without PCOS Using Cardiac Magnetic Resonance

March 16, 2021 updated by: RenJi Hospital
The study is prepared to use CMR technology for early screening of myocardial lesions in 561 age-matched women with type 2 diabetes without PCOS, with PCOS without type 2 diabetes and with type 2 diabetes combined with PCOS, compare the differences between the two groups of cardiomyocyte injury changes, and treat and follow-up with type 2 diabetes and PCOS in accordance with the current standard treatment guidelines for type 2 diabetes and PCOS, after 3 years of follow-up we will analyse the changes in cardiomyopathy, cardiac serological indicators, and heart function indicators,which can provide theoretical basis for early clinical intervention in the future.

Unknown

Conditions

Detailed Description

So far, due to the lack of more sensitive noninvasive detection methods and indicators that suggest early cardiomyopathy, it is not clear whether type 2 diabetes combined with PCOS will lead to earlier and more progressive changes in cardiomyopathy, and whether there is a difference with type 2 diabetes alone and early cardiomyopathy in patients with simple PCOS.Compared with women with type 2 diabetes who did not combine polycystic Ovary Syndrome(PCOS) or PCOS did not combine with type 2 diabetes, patients with type 2 diabetes who combined PCOS had the characteristics of lower age of onset, longer exposure to high risk factors of CVD, and higher risk of cardiovascular disease on the basis of the dual pathophysiology of insulin resistance and hyperandrogenism.The purpose of this study is to find early cardiovascular disease of women with type 2 diabetes and PCOS and conduct early clinical intervention.

Design Details

Cohorts and Interventions

Group / Cohort
type 2 diabetes without polycystic ovary syndrome
The treatment of type 2 diabetes is based on the Chinese Medical Association Diabetes Branch '2017 China Type 2 Diabetes Prevention Guidelines' for lifestyle adjustment and diabetes drug treatment.The research physician decides the diabetes treatment measures of the research object; the blood sugar control goal is that glycosylated hemoglobin is less than 7%.
polycystic ovary syndrome without type 2 diabetes
The treatment of polycystic ovary syndrome is based on the '2018 Polycystic Ovary Syndrome Chinese Diagnosis and Treatment Guidelines' by the Endocrinology Group of the Obstetrics and Gynecology Branch of the Chinese Medical Association and the Guide Expert Group '2018 Polycystic Ovary Syndrome Expert consensus on diagnosis and treatment of endocrinology' for lifestyle and drug treatment.
polycystic ovary syndrome with type 2 diabetes
Treatment is as above.
