Why is everyone reading this as coffee=good. It says lower blood pressure but similar arterial stiffness. It's the arterial stiffness that kills you, not the blood pressure. Blood pressure is normally a symptom of arteriosclerosis. This says coffee hides that symptom, but that only mask the underlying condition.

People in the future will look at us as barbarians for what we do to animals, and maybe we are, but it’s true to that without these methods, we may never gain this knowledge.

I was curious how animals such as rats, dogs, monkeys etc might be given heart attacks, and found the following, which may be of interest to others who are similarly curious.

"Myocardial infarctions (MIs) in rats were originally induced by the sequential administration of subcutaneous isoproterenol causing diffuse myocardial necrosis. Subsequent investigators used an electrocautery technique applied to the epicardial surface to induce small, focal infarctions. Soon thereafter, Pfeffer et al developed the rat coronary ligation model that became perhaps the most widely used heart failure and MI model in the decades to follow."

Apparently transgenic animals can also be used, bred to carry mutated genes so that they develop hypertension, hypertrophy and subsequent heart failure.
