I am female, 47 y/o, 5'5, 128 lbs. I eat mostly whole foods, but had no exercise routine, thin but very unfit. I quit smoking 2 weeks ago, 1-pack/day. Family history of very low blood pressure and heart attacks at very young age (father/37, brother/42, others) but they were in superior physical condition.
2 months ago I had a treadmill stress test (electro not echo).Test was stopped in 8th min due to extreme dizziness. Blood pressure had dropped to 80/60.
