To estimate the relative risks of acute myocardial infarction (MI) and of stroke in postmenopausal users of estrogen/progestogen (E/P) combinations and to estimate the relative risks of MI and of stroke in users of estrogen alone.
Post-menopausal hormone use is becoming increasingly widespread based on evidence of the benefits of estrogen use for bone and the heart. However, because estrogen alone substantially increases the risk of endometrial cancer, estrogen users who have not undergone a hysterectomy are frequently also placed on a progestogen (E/P), a strategy that reduces the likelihood of endometrial cancer when compared with use of estrogen alone. In 1991, there were almost no data on the risk of cardiovascular disease in post-menopausal women who used E/P combinations.
The study had a case-control design, Cases were women hospitalized with MI or stroke in any of nine participating Northern California Kaiser Permanente hospitals in a 36 month period. For each case, one control, matched by year of birth, was selected at random from among members of the Kaiser Permanente Health Plan who were expected to use the same nine hospitals for their medical care. Information about use of estrogen, E/P combinations, past use of oral contraceptives, menopause, hysterectomy and oophorectomy, demographics, general health status, preventive health care, and cardiovascular risk factors were collected in interviews done of the subjects or, for fatal cases, a surrogate. Information about then current use of estrogen and E/P combinations were also gathered by reviewing medical records.
The investigators used conditional logistic regression analysis to estimate the relative risks of MI and of stroke in users of E/P combinations, taking into account prior oophorectomy and other potential confounders. They also estimated the risks of acute MI and of stroke in users of estrogen alone, accounting for prior oophorectomy and potential confounders.

Pathological conditions involving the CARDIOVASCULAR SYSTEM including the HEART; the BLOOD VESSELS; or the PERICARDIUM.
Methods and procedures for the diagnosis of diseases or dysfunction of the cardiovascular system or its organs or demonstration of their physiological processes.
Diseases of long duration and generally slow progression. The four main types of noncommunicable diseases are CARDIOVASCULAR DISEASES (e.g., heart attacks and stroke), CANCER, chronic respiratory diseases (e.g., CHRONIC OBSTRUCTIVE PULMONARY DISEASE and ASTHMA) and DIABETES MELLITUS.
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
