Hypertension and related diseases are a global burden of cardiovascular disorders. Ischemic heart disease and cardiovascular disease rank fourth and fifth among the 10 leading causes of mortality worldwide. A generation from now, these diseases will be an epidemic for which we should be ready and against which we should attempt to find the best preventive measures. ⋯ The newest guidelines from national and international societies have a unifying goal of controlling cardiovascular burden. Guidelines of the international societies are written for a worldwide audience, including countries with very variable health care systems. However, the supreme goal is universal - to lower blood pressure and other risk factors to reduce the risk of cardiovascular disease with its fatal consequences.

Review Case Reports
Isolated pulmonic valve endocarditis in healthy hearts: a case report and review of the literature.
The case of a 53-year-old man with isolated pulmonic valve endocarditis in a structurally normal heart is presented. The patient had a history of chronic obstructive pulmonary disease and was admitted to hospital with an apparent exacerbation with pneumonia. ⋯ The literature from 1960 to 1999 identified only 36 reported cases of pulmonic valve endocarditis in structurally normal hearts. The present report underscores the importance of suspecting pulmonic valve endocarditis in patients with multiple pulmonary lesions, and discusses the predisposing factors, clinical features, diagnostic role of echocardiography and the potential benefits of early surgical treatment.

Comparative Study
Aortic valve area discrepancy by Gorlin equation and Doppler echocardiography continuity equation: relationship to flow in patients with valvular aortic stenosis.
In vitro studies have shown a discrepancy between aortic valve area (AVA) measurements derived invasively by Gorlin equation (Gorlin AVA) and noninvasively by Doppler echocardiography (Doppler-echo) continuity equation (Doppler AVA) during low flow states. ⋯ A flow-related discrepancy between Gorlin AVA and Doppler AVA occurs in the clinical setting of patients with isolated valvular aortic stenosis. This discrepancy should be considered when assessing aortic stenosis severity during low flow states, where Gorlin AVA may be significantly smaller than Doppler AVA.
