Why Are Mauritians at High Risk of Heart Disease

Heart disease is still a very serious issue for the people of Mauritius. In spite of advances in health care, awareness campaigns for heart health and better access to health care facilities, cardiovascular diseases continue to take hundreds of lives and create huge stress on families and communities throughout the island of Mauritius.

According to many public health experts, cardiovascular disease is the cause of approximately 38% of the deaths that occur in Mauritius. This means that approximately 4 out of 10 people die from heart-related issues. While these statistics are frightening, it is important to understand why people are dying from them if we want to prevent further deaths from these conditions.

There are different reasons for the large number of people in Mauritius who have heart disease: diabetes, family history or genetics of heart problems, their lifestyle choices and their food habits. By looking at the above factors, Mauritians can better understand what factors may put them at risk for developing heart problems and then take action to prevent heart disease.

Heart Disease Burden in Mauritius

Cardiovascular diseases include many different conditions related to the heart and blood vessels, such as Coronary artery disease, Myocardial Infarction, Heart Failure, Dysrhythmia, and Stroke.

A modern lifestyle typically involves less physical activity, increased consumption of processed foods, longer working hours, and increased stress; all of these contribute to an increased risk of cardiovascular disease.

According to a study,"The prevalence of coronary heart disease (CHD) was determined in a population survey in Mauritius where the prevalence of non-insulin dependent diabetes and mortality from CHD are amongst the highest in the world. Men and women aged 35-74 years of all major ethnic groups were included: Asian Indians (Hindus and Muslims), Creoles and Chinese. ECG abnormalities suggesting either 'probable CHD' or 'possible CHD' were defined using standard criteria. The overall prevalence of probable CHD was 2.7% in men and 0.9% in women, and that of probable or possible CHD together 17.8% in men and 33.3% in women."

The high rate of deaths caused by heart disease indicates that there is a need for increased awareness, early diagnosis/screening, and preventive healthcare.

A Strong Link Between Diabetes and Heart Disease

Diabetes is one of the primary reasons that Mauritians have a much higher risk of heart disease.

Type 2 diabetes affects how the body can manage blood glucose levels, leading to long-term damage to blood vessels and organs.
Those with diabetes are much more likely to develop problems with their heart and blood vessels than someone without diabetes.
High glucose levels damage the inner lining of blood vessels, increase inflammation, and accelerate plaque accumulation.

All of these things cause arterial narrowing and impede blood flow to the heart over time.

Diabetes is also associated with other risk factors for heart disease, such as:

High blood pressure
High cholesterol
Obesity
Chronic inflammation
Kidney disease

Having these risk factors together will significantly increase the chances of a heart attack or stroke. For many Mauritians and particularly Indo-Mauritians, both diabetes and heart disease are interrelated diseases that must be continually managed and monitored.

The Effects of Current Dietary Habits

Eating excessive amounts of the aforementioned food will contribute to:

Obesity
Experiencing high levels of cholesterol
Having elevated blood pressure
Having diabetes
Experiencing inflammation

Collectively, these factors have increased a personâ€™s risk for developing heart disease. Maintaining a well-balanced diet is one of the most effective ways to influence an individualâ€™s heart health (and longevity).

Is There a Genetic Component?

Genetics is not the only determinant of a person's future health, but inherited traits can influence how fats are processed in the body, where they are stored, and how the blood uses those stored fats.

According to a study, "Genome-wide scans on Indo-Mauritian patients show significant links between early myocardial infarction (heart attacks before age 52-60) and loci on chromosome regions 16p-13, 10q23, and 3q27, which directly influence abnormal glucose and LDL/HDL cholesterol metabolism."

Several individuals in Mauritius may have an increased chance of developing cardiovascular disease by living an unhealthy lifestyle. Additionally, genetic predispositional characteristics arenâ€™t equivalent to predestination. When you live healthily, the chances of developing heart disease dramatically decrease, regardless of your family history of heart disease.

Physical Inactivity: A Growing Concern

Many adults today spend all day sitting at their desks in front of a computer or driving in a car, while children and teenagers are often less likely to engage in outdoor recreation than previous generations.

Inactivity can lead to a variety of negative outcomes, including:

Gaining weight
Losing cardiovascular fitness
Having high blood pressure
Not being able to control your blood sugar levels
Having high cholesterol levels

Regular exercise will help develop a more vibrant heart, improve circulation, assist with blood sugar control, and help maintain a healthy weight. Even moderate amounts of exercise (such as brisk walking, bike riding, swimming, and gardening) can result in considerable cardiovascular health improvements when done consistently.

Understanding the Influence of Stress

Stress is something that is usually not given much thought when discussing the development of heart disease; however, it can have a major influence on cardiovascular health.

Chronic stress caused by work-related pressure, money concerns, family obligations, and everyday troubles creates chronic stress over time.
This increases blood pressure, disturbs sleep patterns, encourages poor eating habits, leads to smoking and/or drinking too much alcohol, and/or creates an environment for developing cardiovascular disease.
Stress also triggers the production of hormones that can cause additional inflammation and increase the workload on your cardiovascular system.

Although there is no way to completely avoid stress, you can use healthy coping mechanisms like exercise, meditation, quality of sleep and social support to alleviate some of its damaging effects.

Tobacco and Alcohol Consumption

Tobacco is considered to be one of the leading causes of CVD for both sexes globally and is therefore very preventable.

Tobacco causes damage to blood vessels, decreases oxygen flow, increases blood pressure and accelerates the development of arterial blockage; in addition, if you inhale tobacco smoke (second-hand), it will also negatively affect your heart.

Excessive alcohol consumption may also lead to high blood pressure, irregular heart rhythms, weight gain, and damage to the heart muscle.

Being smoke-free and drinking alcohol in moderation can significantly lower the risk of CVD.

The Importance of Early Detection

Many CV diseases are chronic, develop slowly, and may not show signs or symptoms until significant damage has occurred. Routine screening for common risk factors can identify potential health problems before complications develop. Some of the most common screening tests include:

Monitoring blood pressure
Testing for blood glucose
Cholesterol testing
Body mass index
Cardiac evaluations as indicated

Early diagnosis gives individuals the opportunity to make lifestyle changes and to be treated by a physician before any major CV events occur.

Protecting Heart Health

While heart disease is one of the leading health problems worldwide, most heart problems can be prevented through education and making healthy lifestyle choices.

Steps that can be taken to maintain heart health include:

Adhere to a well-balanced diet
Participate in physical activity on a regular basis
Control blood sugar levels with proper management of diabetes
Keep blood pressure and cholesterol in check
Do not use any tobacco products
Limit alcohol consumption
Control your level of stress
Attend regular follow-up appointments for healthcare services

Education provided to communities and public health programs in Mauritius is also important in encouraging residents to develop heart-healthy behaviours.

In conclusion

There is no denying that heart disease is a major health concern for the people of Mauritius. There are many factors that can contribute to the high prevalence of heart disease in that region, including diabetes, genetics, eating habits, lack of exercise, stress, and other lifestyle risk factors. The shocking statistic that almost 38% of all deaths in Mauritius are attributed to cardiovascular disease lends urgency to the need for more awareness and prevention.

Many risk factors cannot be changed; however, efforts can be made to manage many of them through healthy lifestyle choices and routine medical visits. By understanding the risk factors for cardiovascular disease and implementing preventive measures, Mauritians can dramatically improve their heart health and ultimately reduce the impact of heart disease on future generations.
