Sir/Madam, On 29th September, 2020 three stents were placed in 2 arteries (blockages were 99%, 96% and 80%). I have been adhering to the diet and medications prescribed by my doctor. However, I have not stopped experiencing acute shortness of breath, heaviness of chest and fatigue. I am unable to  come back to normalcy and any slight activity renders me breathless. Kindly suggest what I should do to be and feel healthy again. Thank you.
