According to Myerburg and Costellanos, the introduction of cardiac revascularization to medicine (coronary artery bypass grafting [CABG]) almost 50 years ago led to a decline in the age-adjusted mortality from coronary artery disease (CAD),1 but brought no change to the fraction of coronary deaths that are sudden and unexpected.1 Of the 650,000 who die annually in the US of CAD, 300,000–350,000…

Heart disease, specifically coronary artery disease (CAD), is the leading cause of death and disability among both men and women in the US. Reductions in blood supply due to narrowings of the arteries that supply the heart muscle with oxygen and nutrients (coronary arteries) result in chest pain and shortness of breath and may lead to permanent scarring of the heart muscle, as in the setting of a…

Cardiac output (CO) is a fundamental measure for the assessment of cardiac performance and is applied widely to detect the presence of cardiovascular disease and monitor its progression, as well as to monitor patients in challenging hemodynamic circumstances and to optimize therapy. CO is a key parameter in characterizing a patient’s hemodynamic state. For example, a notable characteristic of…

Why Do We Need Risk Stratification Tools?
Sudden death accounts for between 300,000 and 500,000 deaths each year in North America.1 Patients with a history of myocardial infarction (MI) have a four-fold higher risk of sudden death than those without such a history. Most sudden deaths in ambulatory populations result from life-threatening ventricular arrhythmias that lead to a cardiac arrest.2…

A significant amount of data has accumulated over the past 20 years, demonstrating the value of exercise or pharmacologic stress non-invasive cardiovascular imaging techniques for the diagnostic and prognostic assessment of patients with suspected or known cardiovascular disease.1-8 Stress can be induced by either multistage exercise testing that is symptom-limited or by pharmacologic means with…

Cardiac computed tomography (CT) has evolved greatly over the last 20 years. This article reviews its current clinical uses, and describes some of the potential for even greater utility in the near future. Electron beam tomography (EBT) was developed 20 years ago specifically for cardiac imaging. Although the technique can quantify ventricular anatomy and function1 as well as myocardial…

Congestive heart failure (CHF) is the number one hospital discharge diagnosis for older adults and the leading cause of hospital readmissions, reflecting poor quality of life for patients and increased healthcare resource use, and is the cause of 300,000 deaths annually.1 Cardiac resynchronization therapy (CRT) has become a new effective treatment modality in those with drug-resistant advanced…
