Epidemiology and Demographics of Unstable Angina / Non ST Elevation Myocardial Infarction
Over 9 million patients in the United States alone have angina. An estimated 80,700,000 American adults (one in three) have one or more types of cardiovascular disease (CVD), of whom 38,200,000 are estimated to be age 60 or older. Except as noted, the estimates were extrapolated to the U.S. population in 2005 from NHANES 1999–2004. (Total CVD includes diseases in the bullet points below except for congenital heart disease). Due to overlap, it is not possible to add these conditions to arrive at a total. [1] [2] [3]
- Hypertension: 73,000,000
- Coronary heart disease: 16,000,000
- Myocardial infarction: 8,100,000
- Angina pectoris: 9,100,000
- Heart failure: 5,300,000
- Stroke: 5,800,000
- Congenital heart disease: 650,000 – 1,300,000
- In 2005, there were 5,812,000 visits to emergency departments in the United States (US) for the evaluation of chest pain and related symptoms.[4]
- In 2007, approximately 700,000 people in the US will have a new myocardial infarction (MI) and about 500,000 will have a recurrent MI.[5]
- In 2007, more than 175,000 people in the US will have a silent MI.[5]
- In 2004, there were 1,565,000 hospitalizations for acute coronary syndrome (ACS) (896,000 for MI, 669,000 for unstable angina (UA) - 21,000 received both diagnoses on discharge).[5]
- Men have a lower average age of first MI than women (65.8 vs. 70.4).[5]
- From 1987 to 2001, the annual age-adjusted rates per 1000 population in the US of first MI were 4.2 for black men, 3.9 for white men, 2.8 for black women and 1.7 for white women, and for new or recurrent MIs in American Indians the rates were 7.6 for men and 4.9 for women.[5]
- There is a 15% rate of death or reinfarction after receiving a diagnosis of UA/non-ST-elevation myocardial infarction (NSTEMI).[6]
The following prevalence estimates are for people age 18 and older from NCHS/NHIS, 2005: [7]
- Among whites only, 12.0% have heart disease, 6.6% have CHD, 21.0% have hypertension and 2.3% have had a stroke.
- Among blacks, 10.2% have heart disease, 6.2% have CHD, 31.2% have hypertension and 3.4% have had a stroke.
- Among Hispanics or Latinos, 8.3% have heart disease, 5.9% have CHD, 20.3% have hypertension and 2.2% have had a stroke.
- Among Asians, 6.7% have heart disease, 3.8% have CHD, 19.4% have hypertension and 2.0% have had a stroke.
- Among Native Hawaiians or other Pacific Islanders, 22.4% have hypertension (other prevalence estimates considered unreliable).
