TL;DR: The morning increase in plasma catecholamines, by further augmenting the direct effects of the sympathetic nervous system, expands the oxygen demand of the myocardium and may lead to plaque rupture or fissure that forms the substrate for thrombus formation as discussed by the authors.

Abstract: also lead to plaque rupture or fissure that forms the substrate for thrombus formation In addition, the morning increase in plasma catecholamines, by further augmenting the direct effects of the sympathetic nervous system, expands the oxygen demand of the myocardium All these factors may be the basis for the precipitation of myocardial ischemia in patients with advanced coronary diseaseg Better understanding of the endogenous biologic functions and the morning physiologic changes of the clinical manifestations of ischemic heart disease may lead to improved control of the precipitating factors and guide toward more effective therapeutic interventions

Twenty-five years in the making: flecainide is safe and effective for the management of atrial fibrillation
TL;DR: There is now a body of evidence that clearly demonstrates that flecainide has a favourable safety profile in AF patients without significant left ventricular disease or coronary heart disease, and fle cainide is now recommended as one of the first-line treatment options for restoring and maintaining SR in patients with AF under current treatment guidelines.

Delayed rhythm control of atrial fibrillation may be a cause of failure to prevent recurrences: reasons for change to active antiarrhythmic treatment at the time of the first detected episode.

TL;DR: Treatment of AF should commence at the first-detected episode and should be based on a double strategy of SR restoration and aggressive treatment of associated conditions that promote atrial remodelling, according to the working hypothesis.
Mechanical remodeling of the left atrium after loss of atrioventricular synchrony - A long-term study in humans
Paul B. Sparks,Harry G. Mond,Jitendra K. Vohra,Anthony G. Yapanis,Leeanne Grigg,Jonathan M. Kalman +5 more
TL;DR: Chronic loss of AV synchrony induced by VVI pacing is associated with mechanical remodeling of the left atrium, which may reverse after the reestablishment ofAV synchrony with DDD pacing, and this process may be partly responsible for the higher incidence of thromboembolism observed in patients undergoing V VI pacing compared with AV sequential pacing.

Role of Echocardiography in Atrial Fibrillation
Tae-Seok Kim,Ho-Joong Youn +1 more
TL;DR: Echocardiography remains the foundation of clinical evaluation and management of AF and other imaging modalities, such as computed tomography and magnetic resonance imaging have complementary roles in risk stratification and assessment of patients with AF.
Incomplete recovery of mechanical and endocrine left atrial functions one month after electrical cardioversion for persistent atrial fibrillation: a pilot study
Anne Bernard-Brunet,Christophe Saint Etienne,Eric Piver,N. Zannad,Jean-Christophe Pages,Laurent Fauchier,Dominique Babuty +6 more
TL;DR: Results suggest that restoration ofleft atrium mechanical function is only partial one month after treatment of persistent atrial fibrillation by electrical cardioversion, whereas a significant reduction of left atrial volume was noted, explaining the remaining high level of ANP in the sinus group.

Circadian variation of blood-pressure
TL;DR: Blood-pressure was highest mid-morning and then fell progressively throughout the remainder of the day and began to rise again during the early hours of the morning before waking.

Concurrent morning increase in platelet aggregability and the risk of myocardial infarction and sudden cardiac death.

TL;DR: The period from 6 to 9 a.m. was the only interval in the 24-hour period during which platelet aggregability increased significantly, and in vitro platelet responsiveness to either adenosine diphosphate or epinephrine was lower.

Circadian variation in the frequency of sudden cardiac death.
TL;DR: The finding that the frequency of sudden cardiac death is increased in the morning is compatible with hypotheses that sudden cardiacDeath results from ischemia or from a primary arrhythmic event, and further study of the physiologic changes occurring in theMorning may provide new information supporting or refuting these hypotheses.

Relation between echocardiographically determined left atrial size and atrial fibrillation.
Walter L. Henry,Joel Morganroth,A S Pearlman,Chester E. Clark,D R Redwood,Samuel B. Itscoitz,S E Epstein +6 more
TL;DR: Left atrial size is an important factor in the development of atrial fibrillation and in determining the long term result of cardioversion, and when left atrial dimension exceeds 45 mm, cardioversion is unlikely to produce sinus rhythm that can be maintained at least six months.
