It’s interesting to note that contraceptives can increase risk of thrombosis. A report in 1980 showed that two women who died of myocardial infarction did not smoke or have hyperlipidemia, hypertension or atherosclerosis; the only connection was an oral contraceptive (1). I’d like to learn more about why this would happen.
