Data from two studies on Patent Foramen Ovale (PFO - a congenital communication between the upper heart chambers) closure with the Amplatzer device, were combined. The combined data demonstrated a significant reduction in migraine symptoms when the communication was closed. The number of migraine days per month and the number of months with migraines were reduced. There were also a greater number of migraine sufferers who were completely relieved of their migraines. The effect was greatest in patients with auras.

About half of patients, in one study, with COVID 19 and elevated cardiac enzymes had evidence of myocardial injury on MRI. 26% of all patients had a pattern suggesting cardiac inflammation. 22% had pattern suggesting a heart attack. 6% had features of both.

89% of all patients had normal cardiac function. 11% had reduced function and of this group only a quarter of them had a serious reduction in cardiac function.

The good news is that half of the affected patients had no defects after 2 months.
