# Calculating DALY for global population

I have been tasked with calculating the DALY. From what I understand, the first part for YLL requires N*L where N is the number of deaths from the decease, and L is the life expectancy at the age of death.

So say I am trying to calculate this for a country like Peru. I am trying to calculate the DALY for heart attacks.

From the data I have found, 2966 people died from a heart attack in Peru. So, the number of deaths (N) was 2966.

The average life expectancy is 72.47, but this I dont think is the correct figure for L. From what I understand, the average life expectancy at the age of death should be the average life expectancy minus the average age of death for heart attacks. First of all, is my thinking correct here?

Second issue is with this if this is the case. How and where would I find the average age of death for heart attacks in a specific country. I have been searching online without success.

Could someone please guide my on how I can calculate the DALY for Peru in relation to heart attacks?
