There was a population based study to take a look at whether FM increases stroke risk using the Taiwan National Health Insurance (NHI) claims database. Which enables people to evaluate a groupe of more than a million people followed with healthy controls over 3 years from January 1, 2000 to December 31, 2002. A total of 47,279 patients with fibromyalgia were studies with 189,112 healthy control
There were co-morbids that occurred like diabetes, IBS, hypertension, hyperlipidemia, coronary heart disease and interstitial cystitis, were more common in patients with fibromyalgia and also associated with a higher risk for stroke. The FM group held a 1.25 fold increased risk of stroke when compared with the controls.
In the absence of comorbids there was still a higher risk of stroke with the FM patients compared to the control group. It was particularly high in younger patients with 2.26 fold relative risk.
Increasing age increased the correlated risk of stroke risk there was presented with FM. But with the younger FM patients the relative risk remained high. The results conclude there is a higher risk of stroke with FM.
