We conclude that the LAA has a characteristic pattern of emptying in sinus rhythm. LAA thrombus formation in sinus rhythm and atrial fibrillation is associated with both poor LAA contraction and LAA dilation.

ED is extremely common in men with chronic coronary artery disease (affecting approximately 75%) yet most cardiologists do not ask about it. The SHIM is a useful, quick and inexpensive tool for discussion and diagnosis of ED in this population. Although it is well established that cardiovascular risk factors are associated with erectile dysfunction, once it is present there is mixed information on whether treating the risk factors will treat the ED. Problems appear to be that lifestyle modification in midlife may simply be too late to effect a change, and some antihypertensive and lipid lowering drugs may actually exacerbate ED. Oral therapy for ED, namely the PDE5 inhibitors, is effective and safe in most cardiac and hypertensive patients. Organic nitrates such as nitroglycerin remain a contraindication to the concomitant use of these drugs. Guidelines for treatment of ED in the cardiac patient issued by the American College of Cardiology/American Heart Association and Princeton Guidelines may be useful in the approach to the cardiac patient with ED.
