Understanding the Causes of Cardiovascular Disease

You must have heard of the phrase, “Take good care of your heart.” Although it is good advice, it is often ignored by most people until something goes wrong. Cardiovascular disease (CVD) is generally seen in later years. Also, the symptoms don’t just appear, but they take time to build quietly. These are shaped by our lifestyle choices, our surroundings, and our genes. 

You must be glad to know that you can prevent the causes of heart disease. To protect your heart, understanding of risks is important. Let’s discuss the cause of prevention of cardiovascular diseases.

When you hear of “heart disease”, you must have thought of only one condition. But there are many forms of cardiovascular diseases. Each type has a different effect on heart or blood vessels. 

• Coronary Artery Disease (CAD): CAD is the most prevalent form of cardiovascular disease. Plaque deposited in the arteries causes CAD, resulting in chest pain or heart attacks.

• Heart Failure:Heart failure does not mean that the heart will stop working completely. But it defines a state where the heart struggles to pump enough blood for the necessary functioning of our body. Some symptoms of heart failure are:

  • Fatigue

  • Swelling in the legs

  • Shortness of breath

• Arrhythmias: Arrhythmias are irregular heartbeats, too fast, too slow, or uneven. Some of these may be harmless. But others can cause a threat to life if not treated on time.

• Stroke: Stroke is often thought of as a “brain problem.” But it is a cardiovascular disease. When the blood does not flow to the brain or blood vessels burst, stroke happens. 

• Peripheral Artery Disease (PAD): PAD usually affects the blood vessels that are outside our heart and brain, especially in the legs, causing:

  • Pain

  • Numbness

  • Circulation problems

• Congenital Heart Disease: These are the birth-time structural problems in the heart. Some of these may be moderate, while some require surgery and lifelong care.

Each of these cardiovascular diseases is triggered by different factors, but they share the same cardiovascular risk factors, such as:

• Unhealthy diet

• Smoking

• High blood pressure

• High cholesterol

• Genetics 

Heart disease doesn’t develop in a day or two. They take years of unhealthy habits, stress, or underlying medical conditions to pop up. The following are some of the key causes of heart disease.

Food is the fuel of your body. An unhealthy diet affects your heart health. You can face heart problems if you take a diet containing saturated fats, trans fats, sugar, and a high amount of salt. Over time, major cardiovascular risk factors can be caused, such as:

• High cholesterol

• Spike blood pressure

• Obesity

Unhealthy foods:

• Fast food

• Fried snacks

• Soda

• Processed meats

• Desserts

Impact:

• Plaque in arteries

• Restriction in blood flow

Better approach:

• Lean proteins

• Colorful veggies

• Whole grains

• Nuts

• Olive oil

When it comes to diet and heart disease, it’s about the balance and consistency.

We are living in an era where sitting is more than usual, such as desk jobs, cars, mobile scrolling, etc. But this physical inactivity often weakens your heart muscle and reduces blood circulation. It also increases the chance of:

• Weight gain

• Type-2 diabetes

• Hypertension

Key points:

• High blood pressure risks are more when you’re inactive.

• Even small movements can help.

• At least 150 min of exercise per week should be done.

Smoking almost guarantees damage to your heart. Cigarette smoke directly:

• Injures artery walls

• Encourage plaque buildup

• Reduce oxygen in the blood

This causes your heart to work harder with less oxygen.

• The risk of heart attacks is twice in smokers.

• Even secondhand smoke causes a risk of cardiovascular disease.

Also, light alcohol may not be harmful, but heavy drinking can:

• Increase blood pressure

• Damage the heart muscle

• Disrupt normal rhythms

You can’t avoid stress. But prolonged, unmanaged stress can silently kill your heart. Adrenaline and cortisol are released when you’re stressed. Constant, high levels of stress can cause:

• Elevated blood pressure

• Increased heart rate

• More inflammation

Many people smoke, overeat, or drink to cope with stress. But this will multiply the risks of cardiovascular disease. This closely links stress and cardiovascular health.

High blood pressure is often called as silent killer. It damages your arteries as it makes your heart pump harder. Over time, hypertension weakens your heart and increases the risk of:

• Heart failure

• Stroke

• Kidney disease

It is risky because the symptoms are only visible when the blood reaches a very high value. So, it is important to regularly monitor your blood pressure.

You may think of cholesterol as bad, but it is required by our bodies. The problem is with a high amount of LDL (bad cholesterol). High LDL : 

• Sticks to the artery walls

• Causes plaque

• Narrows the blood vessels

HDL (good cholesterol) helps clear it away. 

Your cholesterol levels are influenced by: 

• Improper diet

• Inactivity

• Smoking

• Genetics

If you have a family history, then despite being healthy, you’re prone to cardiovascular risk. Family history of heart problems can make you genetically predisposed to conditions, such as:

• High cholesterol

• Hypertensipon

• Arrhythmias

You can avoid genetic heart conditions by healthy lifestyle, diet, and regular checkups.

You not only get rest while sleeping, but your heart and blood vessels rest and repair during that time. If you’re not having proper sleep for many days, then it may lead to:

• High blood pressure

• Insulin resistance

• Increase in stress hormones

All these affect your cardiovascular system. Improper sleep leads to overworking of your heart without recovery. 

Air pollution poses a serious threat to your cardiovascular system along with your lungs. 

Air pollutants can enter your bloodstream through lungs. Once inside, they:

• Trigger inflammation 

• Narrow blood vessels 

• Increase blood clots

According to research, if you’re more exposed to air pollution, then your chances of heart disease and stroke are high. 

Your immune system protects your body. But when it works for more than usual, it causes autoimmune diseases. A constant state of low inflammation is created by it. 

Over time, is lead to:

• Weakened blood vessels

• Accelerated plaque buildup

• Risks of cardiovascular diseases

Prolonged inflammation in your body can have a major effect on your heart.

Your mouth has a major connection with your heart health. Harmful bacteria can be released in the bloodstream by:

• Gum disease

• Chronic tooth infections

• Ignored dental hygiene 

We can say that brushing and flossing not only makes you smile well, but also supports your heart health. 

Drugs can create problems in your cardiovascular system. They cause:

• Spikes in blood pressure

• Rapid heart rhythms

• Sudden cardiac arrest

Marijuana is a drug that is considered safe. But it can even cause an increased heart rate and strain on the cardiovascular system. Prolonged use causes stress on your heart muscle and blood vessels. 

The best part about heart disease causes are that they are preventable. Following steps can make a difference:

• Take nutrient-rich diet

• Avoid processed foods

• Avoid fried items

• Stretching

• 30 minutes walk

• Exercise 

Your heart will start repairing.

Take moderate amounts of alcohol or avoid it. 

You can stay stress free by doing:

• Yoga

• Meditation

• Journaling

• Nature walks

Regular monitoring of blood pressure, cholesterol levels, and blood sugar should be done. Even small habits when done regularly helps. All you need is a healthy lifestyle with better choices everyday.

Cardiovascular Disease may be killing you from inside. You must be surprised to know but your everyday decisions matter, like what you’re eating, how much you're moving, and how you’re handling stress. All of these will shape the future of your heart health.

Prevention doesn’t mean you have to follow strict rules. But awareness and balance is a must. You can support your heart health by:

• Avoiding soda

• Staying active

• Being calm. 

Even while genes are important, your lifestyle is the key. The earlier you start, you will have a stronger and healthier heart.
