AF recurrence: Continuous monitoring studies show that about 90% of patients have recurrent AF. However, as many as 90% of the attacks were not detected by the patients, and asymptomatic attacks lasting more than 48 hours were not uncommon. A report using continuous monitoring showed that 17% of these patients. Later studies also showed that 40% of patients developed AF-like symptoms without AF.
Embolism: systemic circulation embolism, especially stroke, is the most common serious complication of AF.
Asymptomatic cerebral ischemia (SCI) refers to imaging findings of specific lesions without clinical symptoms or characteristics. The radiographic findings of these lesions are consistent with those of cerebral infarction.
It is not clear whether AF attack is an acute trigger of stroke or a marker of left atrial dysfunction, which increases the risk of stroke. It is not clear whether AF attack is an acute trigger of stroke or a marker of left atrial dysfunction, which increases the risk of stroke. An analysis of the ASSERT test focuses on this issue. This study shows that in subclinical AF patients with stroke, very few of them had an AF attack within one month before the embolism event. Another concern is that the risk of atherosclerosis is also higher in patients with paroxysmal AF at higher risk of stroke, and as mentioned above, these patients may have other non-cardiac causes of stroke, especially aortic plaque.
Both men and women, AF is an independent risk factor for mortality over a large age span. But we and other experts believe that there is insufficient evidence to classify AF as a cause of death. The following studies illustrate the scope of risk:
The randomized controlled AFFIRM trial compared heart rate control and rhythm control therapy in AF. The secondary analysis of the trial suggested that sinus rhythm was associated with a significant reduction in mortality (HR 0.53). The DIAMOND test compared dofepride with placebo in patients with left ventricular dysfunction
