Well done indeed! Stopping smoking is the best gift you have given yourself and your family this New Year! You probably feel a better sense of smell and taste. By now more oxygen is reaching your heart and muscles easily and your immune function and circulation are getting better. However it will still be a while before risk of heart disease drops significantly (up to 2 to 5 years) and will take longer (up to 10 to 15 years) to approach that of a non-smoker.
Recovery time after an angioplasty is pretty similar in most parts of the globe. In terms of recovery we generally aim for a 4 to 6 week period to get back to full activity. Usually the cardiac rehabilitation team will come to meet you if you have been admitted with a heart attack and following the angioplasty procedure they will provide guidance on the do’s and dont’s.
How do cardiologists determine what percentage of the coronary artery is blocked during an angiogram, and what is the significance of this?
The coronary angiogram is the current gold standard to establish the degree of coronary artery disease and with experience one can usually determine the stenosis with just “eyeballing”. However, I do use adjunct imaging inside the blood vessel itself, and this helps to clearly establish the area and character of the narrowing or stenosis in the coronary vessel. Evidence from trials clearly show that a narrowing is critical when it approaches 70% as it affects blood flow to the heart muscle.
