Diastolic Dysfunction
Low-intensity exercise may fail to preserve heart health in long-term space travelers
Sustained, low-intensity exercise may not be enough to preserve left ventricular mass and diastolic diameter in long-term space travelers, according to a research letter published in Circulation.
In older patients with HFpEF, worse outcomes for women than men
Female sex was independently associated with diastolic dysfunction and worse clinical outcomes in a cohort of older patients with HF with preserved ejection fraction, researchers reported.

Grading Diastolic Murmurs
Diastolic murmurs are graded on a scale of 1 to 4, while systolic murmurs are graded on a scale of 1 to 6.
Causes of weight gain, higher BP identified in college football players
Weight gain and increased systolic BP in collegiate U.S. football players may be due to concentric left ventricular hypertrophy, arterial stiffening and reduced left ventricular diastolic function, according to a study published in JAMA Cardiology.

Diastolic Mitral Regurgitation
Diastolic mitral regurgitation can occur in the setting of complete heart block when the atrium contracts early after ventricular contraction resulting in a prolonged left ventricular filling period increasing LV pressure toward end-diastole despite a lower left atrial pressure.

Hypertrophic Cardiomyopathy Topic Review
The hypertrophic cardiomyopathies include several diseases with different etiologies, all of which are characterized by abnormal thickening of the myocardium, most commonly in the interventricular septum.

Diastolic Dysfunction
Diastolic dysfunction occurs when the left ventricular myocardium is non-compliant and not able to accept blood return in a normal fashion from the left atrium.

Dock's Murmur
Dock’s murmur occurs when there is a severe stenosis of the left anterior descending coronary artery. The murmur produced is diastolic since the coronary arteries fill in diastole.

Bernheim Effect
The Bernheim effect describes right heart failure developing prior to left heart failure in patients with aortic stenosis due to the hypertrophied ventricular septum bulging into the right ventricle impairing right ventricular diastolic function.
