Everybody knows of somebody who had a sudden heart attack. Heart disease is truly the most dreaded health problem in modern life even in people who are living a reasonably healthy life.  So is heart disease an unforeseen catastrophe, which can strike you out of the blue or can you actually predict your risk and do something about it. 

The World Health Organization stated in 2010 that 80% of premature heart disease, stroke and diabetes can be prevented by a healthy lifestyle.  A British study called the Whitehall study on 19000 healthy office-goers found that those with a healthy lifestyle and healthy parameters like Blood pressure, blood sugar and weight had on average a 10 year longer life than those who do not.  It should, therefore, be obvious that we should know about the health of our heart and how to improve it.  This will “add years to our life” and also “add life to our years”. 

We present a simple scheme showing you how this is actually possible. It is based on an initiative by American Heart Association called Life’s Simple Seven, but it is equally applicable to Indians.

What is Life’s Simple Seven?

Life’s Simple Seven lists 7 simple questions that you should be able to answer about your lifestyle and health status. It consists of four health-related behaviours – smoking and tobacco, healthy diet, adequate exercise and maintaining a healthy weight. Additionally, 3 things that you have to measure are – blood pressure, blood sugar and serum cholesterol.

Your answer can be rated to carry 0, 1 or 2 points.  Score calculation: 2 points for ideal, 1 point for intermediate and 0 points for poor quality. These calculations are then added and the total score will identify 3 ranks of lifestyle health, 10-14 being optimal, 5-9 being average, and 0-4 being inadequate. Research has revealed that the overall lifetime risk for heart failure among adults aged from 45-64 is only 14.4% if they fall into the optimal category, 26.8% for average, and an alarming 48.6% for those in the inadequate category.

Area Definition

(Score: 2 points = Ideal; 1 point = Intermediate;
0 points = poor quality)

STAYING ACTIVE  Physical exercise and activities
strengthen your body, mind and reduce your risk for
cardiovascular issues. Find exercises and activities you
enjoy and can engage with at least 12 times per month and
consult with your primary care physician if you are just
2 points for 150 minutes moderate activity or 75 min
vigorous activity per week. 1 point – less exercise, and 0
points for none

What constitutes a healthy diet has
become controversial of late.  However, you should  Eat a
healthy balanced diet with less salt and sugar, avoid fast
 foods, take plenty of fruits and vegetables.  Fat intake is
 permissible but watch the calories. Non-veg foods are
also healthy with an emphasis on white meat and eggs.  Milk
and milk products are important sources of protein in the
Indian diet

2 points for a healthy diet, 1 point for intermediate diet,

0 points for unhealthy diet – if you don’t take a balanced


Calculate your Body Mass

 Index (BMI). It is a close approximation of body fat and is

a better guide than weight alone.

It is calculated as the weight in kg divided by the square of

the height in metres. 

For Indians, BMI should be  below 23 (2 points)

BMI > 23-28 scores 1 point

BMI >28 is unhealthy and scores 0 points

The higher the pressure, the greater

 the risk of damage being caused to your heart and veins

(i.e. hypertension).

Normal BP is <120/80 without treatment (2 points)
Score 0 points if BP is >140 upper or> 90 lower value

with or without treatment. 
Score 1 point for intermediate values or even for normal

value with treatment
BLOOD CHOLESTEROL  there are 2 types of
cholesterol: low-density lipoprotein (LDL) and
high-density lipoproteins.  Although cholesterol is
essential for your body to function properly, an unhealthy
amount of LDL cholesterol may clog your arteries.Score
2 points for total cholesterol <200 mg/dl, 1 point for
200-240 mg/dl and 0 points for higher values

knowing your blood sugar is just as
 important as knowing your blood pressure and cholesterol.

Prediabetes can be managed with diet and exercise and this can help you to avoid prediabetes treatment at hospital while diabetes usually needs drugs. Risk of heart disease is raised even with prediabetes

If you are not fasting, glycosylated Hemoglobin can be

measured to denote the 3-month average glucose level.

FPG (Fasting plasma glucose ) <100 mg/dl or
HbA1c <5.7% is ideal and scores 2 points

FPG 100-120 or HbA1c 5.8-6.4 gets 1 point

FPG >120 or HbA1C> 6.5 increases risk – 0 points


Inhaled or oral tobacco damages almost

 every organ in your body, and the chemicals in tobacco can

 harm the structure and function of your blood vessels and

damage your heart. This even applies to the e-cigarettes

which are being promoted today

 2 pts for no tobacco/smoking (Never or left >12 months)

1 pt for those who have quit < 12 mon ago

0 pt for current users
