    Genetic support for the causal role of insulin in coronary heart disease.

    Epidemiological studies have identified several traits associated with CHD, but few of these have been shown to be causal risk factors and thus suitable targets for treatment. Our aim was to evaluate the causal role of a large set of known CHD risk factors using single-nucleotide polymorphisms (SNPs) as instrumental variables.


    Based on published genome-wide association studies (GWASs), we estimated the associations between the established risk factors (blood lipids, obesity, glycaemic traits and BP) and CHD with two complementary approaches: (1) using summary statistics from GWASs to analyse the accordance of SNP effects on risk factors and on CHD; and (2) individual-level analysis where we constructed genetic risk scores (GRSs) in a large Finnish dataset (N = 26,554, CHD events n = 4016).

    We used a weighted regression-based method for summary-level data to evaluate the causality of risk factors. The associations between the GRSs and CHD in the Finnish dataset were evaluated with logistic and conditional logistic regression models.


    The summary-level data analysis revealed causal effects between glycaemic traits (insulin and glucose) and CHD. The individual-level data analysis supported the causal role of insulin, but not of glucose, on CHD. The GRS for insulin was associated with CHD in the Finnish cohort (OR 1.06 per SD in GRS, 95% CI 1.02, 1.10, p = 0.002).


    These results support the causal role of insulin in the pathogenesis of CHD. Efficient treatment and prevention of insulin resistance is essential to prevent future CHD events.

    Type two diabetic-low carb diet (50 carbs per day) and two 500mg Metformin pills per day. Apart from diagnosis HbA1c almost 12-all HbA1c results none diabetic. For over eight years my diabetes medication has not changed. My weight has remained stable, I have suffered no ill effects from my diet whatsoever. Every blood test has proved, I took the right road to my diabetic salvation. For almost seven years, I have asked medical professionals and naysayers, how do I maintain non diabetic BG levels on two Metformin other than low carb ? The silence has been deafening !

    And how do they treat diabetes? By increasing insulin to reduce the BG. No wonder trials like ACCORD are so unsuccessful.

    Of course the likes of Joseph Kraft had this sussed decades ago before "cholesterol" got the blame for everything. Nice to see the wheel turning back.
