The Massachusetts ME/CFS & FM Association, a 501(c)3 founded in 1985, exists to meet the needs of patients with ME (Myalgic Encephalomyelitis), CFS (Chronic Fatigue Syndrome) or FM (Fibromyalgia), their families and loved ones. The Massachusetts ME/CFS & FM Association works to educate health-care providers and the general public regarding these severely-disabling physical illnesses. We also support patients and their families and advocate for more effective treatment and research.

Over the past several years, in a number of small studies, Dr. A. Martin Lerner and his collaborators at Wayne State University and the University of Michigan have objectively documented heart symptoms and abnormalities in a percentage of Myalgic Encephalomyelitis/chronic Fatigue Syndrome (ME/CFS) patients.
In one study, the administration of intravenous ganciclovir had a marked effect in a subset of ME/CFS patients in increasing their ability to function.
Studies 1 and 2 cited below objectively documented intermittent tachycardia in a very high percentage of CFS patients. The tachycardia is accompanied by T-wave abnormalities as measured by 24-hour Holter monitoring.
CFS patients for these two studies were selected from infectious disease practices, were younger than 50, and did not have any known heart or circulatory condition. Patients experienced left-sided chest pain, palpitations, rapid pulse and light-headedness.
Lerner found that, "In CFS patients, oscillating abnormal T-waves were regularly seen with the onset of sinus tachycardias, and the abnormal T-waves then resolved with the reappearance of normal sinus rhythms." 1
"This study 2 confirms our earlier report 1, just quoted that CFS patients uniformly have abnormal oscillating T-wave flattenings and T-wave inversions by Holter monitoring."
In this study, 96% of 51 CFS patients (1988 and 1994 diagnostic criteria) had one or both of the T-wave abnormalities. The studies found that 12 lead standard ECGs and 2-D echocardiograms do not generally show these cardiac abnormalities in CFS.
In a new unpublished study 4, the researchers found "... 24% of 87 non-selected CFS patients from a recent consecutive case series exhibited left ventricular dysfunction, by stress radioscopic multiple gated acquistion (blood pool image) (MUGA) method. Abnormal cardiac wall motion at rest and stress, dilation of the left ventricle, and segmental wall motion abnormalities were present.
These abnormal ejection fractions demonstrate abnormal left ventricular function and are not seen with normal persons living a sedentary lifestyle."
In another study 3, 18 CFS patients were given the anti-viral ganciclovir intravenously for 30 days. A subset of patients, ill for an average of 1.6 years and with somewhat elevated CMV (cytomegalovirus) anti-body titres, experienced substantial improvement in overall ability to function. This study, "was not blinded, randomized, or placebo-controlled."

Notice about names
The Massachusetts ME/CFS & FM Association would like to clarify the use of the various acronyms for Chronic Fatigue Syndrome (CFS), Chronic Fatigue & Immune Dysfunction Syndrome (CFIDS) and Myalgic Encephalomyelitis (ME) on this site. When we generate our own articles on the illness, we will refer to it as ME/CFS, the term now generally used in the United States. When we are reporting on someone else’s report, we will use the term they use. The National Institutes of Health (NIH) and other federal agencies, including the CDC, are currently using ME/CFS.
Massachusetts ME/CFS & FM Association changed its name in July, 2018, to reflect this consensus.
