  3. Racial/ethnic differences in the prevalence of atrial fibrillation among older adults--a cross-sectional study.

    Journal of the National Medical Association 102(10):906 (2010) PMID 21053705

    Atrial fibrillation affects 4% to 8% of individuals over 60 years of age based on studies of predominantly white populations, whether this is true among nonwhite individuals is not clear. This study was undertaken to define racial/ethnic differences in atrial fibrillation prevalence among a larg...
  4. Racial/Ethnic differences in ischemic stroke rates and the efficacy of warfarin among patients with atrial fibrillation.

    Stroke 39(10):2736 (2008) PMID 18635860

    Warfarin reduces stroke risk in studies of predominantly white patients with atrial fibrillation (AF). Whether nonwhites also have lower rates of stroke while treated with warfarin is unclear. A multiethnic stroke-free cohort hospitalized with nonrheumatic AF was identified in a large health mai...
  5. Sodium bicarbonate vs sodium chloride for the prevention of contrast medium-induced nephropathy in patients undergoing coronary angiography: a randomized trial.

    JAMA 300(9):1038 (2008) PMID 18768415

    Sodium bicarbonate has been suggested as a possible strategy for prevention of contrast medium-induced nephropathy, a common cause of renal failure associated with prolonged hospitalization, increased health care costs, and substantial morbidity and mortality. To determine if sodium bicarbonate ...
  6. Long-term outcomes by clopidogrel duration and stent type in a diabetic population with de novo coronary artery lesions.

    Journal of the American College of Cardiology 51(23):2220 (2008) PMID 18534267

    The purpose of this study was to determine whether long-term clinical outcomes differed between bare-metal stents (BMS) and drug-eluting stents (DES) by duration of clopidogrel use among diabetic patients. There is concern that DES are associated with late adverse events such as death and myocar...

  9. Effect of race/ethnicity on the efficacy of warfarin: potential implications for prevention of stroke in patients with atrial fibrillation.

    CNS Drugs 22(10):815 (2008) PMID 18788834

    Atrial fibrillation (AF) is the most common sustained arrhythmia seen in clinical practice. It affects approximately 6% of persons over 65 years of age and is independently associated with a 4- to 5-fold higher risk of ischaemic stroke and a 2-fold higher risk of death. Randomized controlled tri...
  10. Racial/ethnic differences in the risk of intracranial hemorrhage among patients with atrial fibrillation.

    Journal of the American College of Cardiology 50(4):309 (2007) PMID 17659197

    This study was designed to study racial/ethnic differences in the risk for intracranial hemorrhage (ICH) and the effect of warfarin on ICH risk among patients with atrial fibrillation (AF). Nonwhites are at greater risk for ICH than whites in the general population. Whether this applies to patie...
  11. Incidence, mortality, and racial differences in peripartum cardiomyopathy.

    The American Journal of Cardiology 100(2):302 (2007) PMID 17631087

    There are no large population-based studies on the incidence and prognosis of peripartum cardiomyopathy (PC). Between 1996 and 2005, there were 241,497 deliveries within the Southern California Kaiser healthcare system. Among these, we identified 60 cases of PC by searching for an International ...
  12. Racial/Ethnic Differences in the Risk of Intracranial Hemorrhage Among Patients With Atrial Fibrillation

  14. Association of race, heart failure and chronic kidney disease.

    Future Cardiology 2(4):441 (2006) PMID 19804180

    Heart failure and kidney disease are two important emerging epidemics. The importance of pre-end stage kidney disease was introduced in the 2002 publication of the National Kidney Foundation's Chronic Kidney Disease Guidelines. One in nine US adults has some degree of kidney disease, many of who...
