High natural insulin and heart disease

Hyperinsulinemia as an independent risk factor for ischemic heart disease.

Overview

Després JP et al.. N Engl J Med 1996 · PMID 8596596 · DOI 10.1056/NEJM199604113341504

Men with higher fasting insulin had more heart disease.

Does the study support the specific claim? Partly · Methodological quality: moderate

Study explained simply

What did the researchers want to find out?: Is fasting hyperinsulinaemia an independent risk factor for IHD?
How was the study done?: Nested case-control within prospective cohort (Quebec)
How many people, animals or samples were studied?: 2,103 men; 91 cases, 105 controls; Non-diabetic men 45-76
What was actually found?: OR 1.7 per SD.
How large was the observed effect?: OR 1.6-1.7
What do the results mean in everyday life?: Insulin resistance is a heart risk marker.
What are the study's limitations?: Small number of cases; Men only; Endogenous insulin, not therapy
What does it say about Elawady's specific claim?: Association for C-INS-03.
Do the results apply to Germany and Europe?: Canadian men.
What can explicitly not be concluded from this study?: That insulin injections cause heart disease.

Is fasting hyperinsulinaemia an independent risk factor for IHD?

Study design: Case-control study – Nested case-control within prospective cohort (Quebec)
Population: Non-diabetic men 45-76
Country: Canada
Period: 1985-1990
Sample size: 2,103 men; 91 cases, 105 controls
Inclusion and exclusion criteria: As described in the abstract; details not available in abstract.

Results: Fasting insulin 18% higher in cases; OR per SD 1.7 (1.3-2.4); after lipid adjustment 1.6 (1.1-2.3).
Absolute risks: not reported
Authors' conclusion: High fasting insulin appears to be an independent predictor of IHD in men.

Modest association.

Association for C-INS-03.

Canadian men.

Marker association.

Note: according to the archive, the studies were compiled by the archive operators. Whether Dr. Elawady himself cited this study is not established.

What the archive says about the study: Listed in the archive bibliography for 'insulin-injections' without its own interpretation; used as general support for the claim that insulin intensification harms.
A. What was actually studied?: Is fasting hyperinsulinaemia an independent risk factor for IHD?
B. What did the authors find?: OR 1.7 per SD.
C. What conclusions do the authors themselves draw?: High fasting insulin appears to be an independent predictor of IHD in men.
D. What does the archive derive from it?: Support for 'insulin causes atherosclerosis'.
E. Is this derivation scientifically justified?: Not justified for injected insulin; endogenous insulin marks insulin resistance.
Adequacy of the interpretation (by the archive): not supported by the study
