The following paper, based on literature review (not an independent study!) explains the mechanisms behind cardiovascular diseases: cardiomyopathy, endothelial dysfunction, atherosclerotic plaque formation and coronary heart disease. The main cause = insulin resistance!

...epidemiological and pathophysiological studies suggest that hyperglycemia may be largely responsible for CVD. Blood glucose has been reported as an independent predictor of atherosclerosis and blood glucose level greater than 90 mg/dl can lead to atherosclerosis in the carotid artery [125]. Long-term follow up data from patients with type 1 and type 2 diabetes suggest that hyperglycemia is a risk factor for diabetes related diseases and CVDMoreover, it has been suggested by Salvin et al. [126] that a 1 unit increase in the total glycosylated hemoglobin or HbA1C, can increase the risk of CVD by up to 18%. Even in the absence of overt diabetes, impairment in the glucose homeostasis can affect the cardiac autonomic function leading to high risk of cardiac diseases [127].

In this sense, recently it has been shown that cyclic ketone bodies preserve “young cardiac phenotype” in old mice [167]. On the other hand, it has been reported that isocaloric ketogenic diet (very low in carbohydrates and high in fats and/or proteins) increases lifespan [168].
Overall, insulin resistance contributes to generate CVD via two independent pathways: (1) atheroma plaque formation and (2) ventricular hypertrophy and diastolic abnormality.
