Brief Summary:

The primary purpose of this study is to determine the effects of a fixed dose combination of valsartan, hydrochlorothiazide, atorvastatin and aspirin (PolyPill) on prevention of cardiovascular events in adults older than 50.

Various liver-related variables will also be recorded which will allow studying the effects of PolyPill on the liver and the effect of liver diseases such as nonalcoholic steatohepatitis on cardiovascular events and the protective effect of PolyPill.

Condition or disease Intervention/treatment Phase
Cardiovascular Diseases Drug: Polypill Phase 3

Detailed Description:

2400 subjects will be randomly selected from participants of the Golestan Cohort Study (GCS) who are living in Gonbad and are over 50 years old. These subjects will be randomized to either receive PolyPill or no treatment.

Those agreeing to the study will undergo additional measurements (in addition to the baseline measurements performed in the GCS) including liver-related tests such as liver enzyme levels, abdominal ultrasonography and liver stiffness measurement. Some additional tests such as color doppler ultrasonography of carotid vessels will also be performed.

Subjects in the PolyPill arm who have no contraindication for the components of the pill will receive a single daily dose of PolyPill for 5 years.
