Myocardial ischemia silent

In morbidly obese patients (those weighing more than 350 lbs) with LEAD, neither myocardial perfiision studies nor coronary angiography can be performed for technical reasons. These patients can be evaluated with contrast echocardiography (Chapter 9). The management of patients with LEAD and CAD is the same as in every patient who has myocardial ischemia, silent or symptomatic. [Pg.315]

Although angina pectoris is believed to be caused by the buildup of lactic acid and other metabolites, the exact mechanisms responsible for mediating anginal pain remain unknown. Also, the emotional state of the patient and other factors that influence central pain perception play an obvious role in angina pectoris.20,34 In fact, the majority of anginal attacks may be silent in many patients, and myocardial ischemia may ffe-...

Acute coronary syndromes most often result from a physical disruption of the fibrous cap, either frank cap fracture or superficial endothelial erosion, allowing the blood to make contact with the thrombogenic material in the lipid core or the subendothelial region of the intima. This contact initiates the formation of a thrombus, which can lead to a sudden and dramatic blockade of blood flow through the affected artery. If the thrombus is nonocclusive or transient, it may either be clinically silent or manifest as symptoms characteristic of unstable angina. Importantly, if collateral vessels have previously formed, for example, due to chronic ischemia produced by multi vessel disease, even total occlusion of one coronary artery may not lead to an acute myocardial infarction.

It has been convincingly shown that a nitrate-free period reduces nitrate tolerance (72). The modem strategy is to have a nitrate-free period when the patient is asleep, although this results in reduced protection from ischemia in the early morning, the time when many episodes of silent ischemia and myocardial infarction occur. Reports that ACE inhibitors (73) or carvedilol (74) reduce nitrate tolerance are as yet unconfirmed (75). [Pg.2532]

In the elderly, the symptoms of pain, pressure, or tightness, may he modified and more ill defined actually they may be minimal to absent. Similarly, asymptomatic coronary heart disease with silent myocardial infarction and silent ischemia is more prevalent in the elderly. Epidemiologic studies estimate the prevalence of claudication to be as high as 10%... [Pg.8]
