Now my age is 62 yrs.Two years back i underwent an angiography and angioplasty,and two stents installed.Now i took a stress test and it was positive.I stay on the third floor with no lift,so have to climb the steps, 3 to 4 times daily.But still i dont show an symptoms like chest pain,intensive breathing etc.Should i go for a 2d echo or an angiography.Or may be a pet scan,but i dont think a Pet scan may be available in our town.
