Dysphoric milk ejection reflex sense of depression and this feeling can range from mild homesickness or wistfulness to more intense feelings of hopelessness and self-loathing. Similarly, anxiety may range from restlessness to more intense panic and dread. Anger, the least likely of the three, may range from tension and agitation to more intense feelings of hostility and aggression. The mechanism is not clear. In a mother with D-MER, dopamine may fall inappropriately with milk release, causing the negative feelings. Among the hormones involved in milk production and release are oxytocin, prolactin, and dopamine. Oxytocin, released in pulsatile "spikes" from the posterior pituitary in response
Heart failure with preserved ejection fraction the left ventricle can lead to diastolic dysfunction. Other causes of left ventricular stiffening include: Causes of isolated right ventricular diastolic failure are uncommon. These causes include: Structural changes that occur with HFpEF are often radically different from those associated with heart failure with reduced ejection fraction (HFrEF). Many patients experience increased thickening of the ventricular wall in comparison to chamber size, termed concentric hypertrophy. This leads to increased left ventricular mass and is typically accompanied by a normal, or slightly reduced, end diastolic filling volume. Conversely, HFrEF is typically associated with eccentric hypertrophy, characterized by an increase in cardiac
