Document Summary
A person with a type a personality is one who is quite hard-driving, intense, and competitive. People with type a personality have a greater chance of suffering atherosclerosis that those with a type b personality: other psychological stressors. Isolation, pessimism and repressed emotions (type d) and people with low self-esteem and confidence also have a greater incidence (3x) of atherosclerosis: smoking. Smoking leads to a decrease in hdl and an increase in platelet stickiness. Furthermore, the carbon monoxide produced binds to hemoglobin with 250x the affinity of oxygen. Second hand smoke is unfiltered and thus is more cardiotoxic than the smoke that goes inside a smoker"s lungs. Some people have smoked 3 packs a day for 70 yr and have never had a heart problem. People use such individual-type evidence to show that a relation between smoking and atherosclerosis does not exist. This type of evidence has been used to discount many other types of health problems.
