I am 70 years old, weigh 155 and 5 10 female. A year ago I flunked 2 stress tests, and they took me for an angiogram thinking I had a possible 70% blockage. I did not have blockages but my arteries are tortuous. i try to keep moving and keep my heart rate up a little...That blood has a long way to go since i am tall so i do not sit very long at a time. the S curves & turns show up especially in my hands. i was glad i did not need a stent, and so i suppose tortuous arteries is better than blocked arteries. i have never smoked, a walmart wine cooler is about the extent of my drinking occasionally. Anyway, are these arteries going to keep getting crooked enough to perhaps close off blood supply anywhere? i had my yearly check-up. a test monitor for 48 hours showed Premature Ventricular Contractions. i do wonder why i have this condition, how long it took to develop. Will it keep getting worse. Best of all, though...i feel great...just curious about tortuous arteries. Frances, Moore, Oklahoma
