Effects of insulin on heart health

If you have type-2 diabetes there are many ways to receive insulin, such as rapid-acting insulin, short-acting insulin and long-acting insulin. Long-acting insulin can last from 24 to 36 hours after administered. The purpose of long-acting insulin is to provide insulin for the whole day, as opposed to rapid-acting insulin which is intended to reduce spikes in blood sugar post-meal and only lasts for about five hours.

Recent research reveals that the use of long-acting insulin will not increase the risk of myocardial infarction (heart attack) in those with type-2 diabetes. The study comes from researchers at the Leibniz Institute for Prevention Research and Epidemiology in Germany.

Researchers examined data from 21,501 individuals with type-2 diabetes. The participants just began using insulin – some used premixed insulin, some analog insulin and some neutral protamine Hagedorn (NPH).

Findings revealed there was no significant increase in the risk of heart attack from any of the three types of long-acting insulin. The findings were published in Diabetes, Obesity and Metabolism.

Causes of insulin resistance include:

Being overweight

Lack of exercise

Steroid use

Changes in hormones

Some medications

Old age


Sleep problems – sleep apnea
