Abstract

Dobutamine stress echocardiography is frequently used for preoperative assessment of cardiac risk before major vascular surgical procedures. Dobutamine increases myocardial contractility, heart rate, and rate of increase of left ventricular pressure and has a variable effect on blood pressure. These effects could potentially increase the likelihood of rupture of a vascular aneurysm. The safety of performing dobutamine stress echocardiography in patients with vascular aneurysms has not been adequately addressed. Of 1,968 consecutive patients who underwent dobutamine stress echocardiography at our institution, 98 patients with abdominal aortic aneurysms > or = 4 cm in diameter were identified. Records were reviewed to determine whether there was any evidence of aneurysm rupture or adverse vascular events as a result of the stress test. There was no case of aneurysm rupture or hemodynamic instability precipitated by dobutamine stress echocardiography. In addition, dobutamine stress echocardiography that was negative for ischemia identified patients at very low risk of perioperative cardiac events. The positive predictive value of ischemia during dobutamine echocardiography was 29%. Dobutamine stress echocardiography may be perform...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
