Dengue can be deadly for those who have heart disease, says a research study conducted by Upendra Kaul, dean and executive director, Clinical Research and Academics, Fortis Healthcare Limited.

The research states that if someone has dengue fever coupled with chest discomfort, shortness of breath, unnecessary fatigue, the doctor must get ECG or ECHO done to rule out the possibility of heart involvement.

Reports shows ECG and ECHO changes in patients admitted with dengue fever, but with no prior heart ailments.

“We found that those having heart problems were affected by dengue at large and hence creating a double challenge for us to treat them. Simultaneously, those who had dengue, their ECG & ECHO were showing some temporary malfunction of the heart. However, these were corrected with supportive treatment. But it is very important not to overlook any symptoms in both cases.”

Dengue shows its symptoms after 3-14 days of mosquito bite.

HEART DISEASES AND ANGINA PECTORIS

The most common symptom of coronary artery disease is 

angina or "angina pectoris," also known simply as chest pain. 

Angina can be described as a discomfort, heaviness, 

pressure, aching, burning, fullness, squeezing, or painful feeling 

due to coronary heart disease. Often, it can be mistaken for 

indigestion.

Angina is usually felt in the chest, but may also be felt in the 

shoulders, arms, neck, throat, jaw, or back.

If you experience these symptoms, take notice. If you've never 

been diagnosed with heart disease, you should seek treatment 

immediately. If you've had angina before, use your angina 

medications as directed by your doctor and try to determine if 

this is your regular pattern of angina or if the symptoms are 

worse. 

What Causes Angina?

Angina is caused when blood flow to an area of the heart is 

decreased, impairing the delivery of oxygen and vital nutrients 

to the heart muscle cells. When this happens, the heart muscle 

must use alternative, less efficient forms of fuel so that it can 

perform its function of pumping blood to the body. The 

by-product of using this less efficient fuel is a compound called 

lactic acid that builds up in the muscle and causes pain. Some 

medications used to treat angina work by inhibiting the use of 

this fuel source.

What Are the Types of Angina?

The types of angina are:

• Stable angina. The pain is predictable and present only 
• during exertion or extreme emotional distress, and it 
• disappears with rest.
• 
  
• Unstable angina. This may signal an impending heart 
• attack. Unstable angina is angina pain that is different from 
• your regular angina pain or pain that occurs while at rest. The 
• angina may occur more frequently, more easily at rest, feel 
• more severe, last longer, or come on with minimal activity. 
• Although this type of angina can often be relieved with 
• medication, it is unstable and may progress to a heart attack. 
• Usually more intense medical treatment or a procedure is 
• required.

• 
  
• Prinzmetal's angina. This is when angina occurs at rest, 
• when sleeping, or when exposed to cold temperatures. In 
• these cases, the symptoms are caused by decreased blood 
• flow to the heart muscle from a spasm of the coronary artery. 
• The majority of people with this type of angina also have 
• coronary artery disease. These spasms occur close to the 
• blockage.

Can Angina Occur Without Coronary Disease?

Angina can occur in the absence of any coronary disease. Up 

to 30% of people with angina with a heart valve problem called 

aortic stenosis, which can cause decreased blood flow to the 

coronary arteries from the heart. People with severe anaemia 

may have angina because their blood doesn't carry enough 

oxygen. People with thickened heart muscles need more 

oxygen and can have angina when they don't get enough.

How Is Angina Evaluated?

To evaluate your angina, your doctor will first ask you a series 

of questions to determine what your symptoms are and what 

triggers them. After examining you, your doctor will order one or 

more of a series of tests to determine the underlying cause of 

the angina and the extent of coronary artery disease, if present. 

These tests include:

• Exercise Stress Test
• 
  
• Electrocardiogram ( ECG/ EKG)
• 
  
• Stress imaging tests, such as nuclear tests or stress 
• 
  
• echo-cardiography, to accurately localize the part of the heart 
• 
  
• that has decreased blood flow
• 
  
• Echocardiogram
• 
  
• Cardiac catheterization

How Is Angina Treated?

Your angina treatment depends on the severity of the 

underlying problem, namely, the amount of damage to the 

heart. For most people with mild angina, a combination of 

drugs and lifestyle changes can control the symptoms. Lifestyle 

changes include: eating a heart-healthy diet, lowering 

cholesterol, getting regular exercise,quitting smoking, and 

controlling diabetes and high blood pressure.

Some drugs used to treat angina work by either increasing the 

amount of oxygen delivered to the heart muscle or reducing the 

heart's need for oxygen. These medicines include:

• Beta-blockers
• 
  
• Nitrates
• 
  
• Calcium channel blockers
• 
  

Other angina drugs work to prevent the formation of blood 

clots, which can further block blood flow to the heart muscle. 

These medicines include:

• Antiplatelet medications

For people with more serious or worsening angina, your doctor 

may recommend treatment to open blocked arteries. These 

include:

• Angioplasty
• 
  
• Stenting
• 
  
• Coronary artery bypass grafting (CABG) surgery
• Enhanced External Counterpulsation (EECP)

What Should I Do if I Have Angina?

With any type of angina, stop what you are doing and rest.

If you have been prescribed a medication called nitroglycerin to 

treat your angina, take one tablet and let it dissolve under your 

tongue. If using the spray form, spray it under your tongue. Wait 

five minutes.

If you still have angina after five minutes, take another dose of 

nitroglycerin. Wait another five minutes and if angina is still 

present, take a third dose.

If you still have angina after taking a third dose of nitroglycerin 

and resting for 15 minutes, call for emergency help (dial 911 in 

most areas) or have someone take you to the local emergency 

room.

If you think you are having a heart attack, do not delay. Call for 

emergency help right away. Do not drive yourself to the 

hospital. Consider taking an aspirin. Quick treatment of a 

heart attack is very important to lessen the amount of damage 

to your heart.

Why Shouldn't I Drive Myself or Have Someone Drive Me 

to the Hospital?

When the ambulance arrives, the emergency personnel can 

begin to give you heart-saving care right away. They can start 

an IV to give you important drugs and give you oxygen to help 

improve the flow of oxygen-rich blood to your heart. Should 

problems occur, they are there to provide life-saving help as 

well.

Something to Remember About Angina

If you have angina, carry nitroglycerin with you at all times; you 

never know when you will need it. Nitroglycerin must be kept in 

a dark container. Keep it away from heat or moisture. Check 

the expiration date on the container. Once the container of 

nitroglycerin tablets is opened, it must be replaced every three 

months. The spray form has a longer shelf life and should be 

replaced every 2 years.

TIPS TO KEEP YOUR HEART IN GOOD SHAPE

Heed your diet
- Reduce your fat and carbohydrate intake
- Avoid fried foods
- Eat fruits and vegetables
- Keep your oil consumption to no more than 3-4 tsp. per individual per day. Use any oil.

There is nothing to prove that olive oil is a better oil. Whether it is sugar or oil, it's best had in the form nature meant for us to have, like nuts for our oil requirement, and fruits and sugar-cane for sugar. Anything that is had in concentrated form is bad for the system.

- Stay away from red meat; chicken and fish are fine.

Stay active
- Exercise for at least half an hour daily. Exercise is best done in the morning when there is release of some chemical substances in the brain that keeps you active throughout the day. Preferably, exercise on an empty stomach.

- Choose any form of exercise like swimming,  brisk walking, playing a sport; anything that makes you sweat. People who exercise tend to stay younger and more active for a much longer time than people who do not exercise.

At the heart of it
- Every person above the age of 40 must get a 64-slice CT Scan done. This helps detect the presence of heart disease, if any, 10 years ahead of its onset. It helps to detect early onset of coronary artery disease, and is the best tool available today to detect any anticipated heart problem.

- Diabetics and hypertensive people should control their diabetes and hypertension, respectively, as these conditions can lead to heart problems. As much as 16-17% of the population living in cities has diabetes. Hypertension should, ideally, be controlled by exercise and diet, failing which medication is necessary.

- If someone has had a family history of heart disease, or has had a heart attack at a younger age, they're more vulnerable to heart disease. At least once a year, they should go for a routine cardiac evaluation like Echo, ECG, stress test, and blood tests. And once every 3-4 years, they should go for the 64-slice CT Scan.

- Consult a doctor if you have breathing difficulties, chest pain or palpitations.

Soak in spirituality
Everyone should  become spiritual. In any activity that you do in life, there are no guarantees. You can lose your job; you can lose your loved ones. Anything can happen.

What will keep you calm is your belief in a superpower, what we call as God. Know that everything what is fair for you will be done. I am not saying you should be religious, but you should be spiritual. Belief in a superpower will give you the strength to overcome difficulties. We need to have the resolve and strength to wait for the cloud to pass.

Any activity you do, do it in the name of God. Whatever the outcome, it is not in your hand. This approach will calm you down, and you'll be able to perform much better.

Quit Smoking and go easy on alcohol
Smoking is one habit which will definitely land you in trouble. Remember, it's never too late in life to give up smoking. Lot of the injuries you have done by smoking can be reversed by quitting smoking.

Alcohol again can injure you, very significantly, but moderation may not harm you to that level, provided you're able to control it. No alcohol or wine is good for you. To quit smoking you need professional hand holding where psychologists will help you go through it.

 Work hard and try to protect your heart. No doctor in the world can help you if you don't want to help yourself. Do not look at  doctors as saviours. First, don't land yourself in this trouble. Your effort should be to keep away from doctors.
