Coronary Artery Disease - Symptoms and Causes

Coronary artery disease is the disease in which the major blood vessels (coronary arteries) that supply blood, nutrients and oxygen to your heart get damaged or disease stricken. It is mostly caused due to the coronary artery getting plagued or inflamed. The consequent reduction in blood flow to the heart causes the various symptoms of coronary artery disease like angina (chest pain), short breath etc.

Symptoms:

Here is a list of a few symptoms that help in identification of the coronary artery disease.

1. Angina

Pressure or tightness may be felt in or near the area of the chest that results in pain. It is mostly felt in the middle or left side of the chest.

2. Shortness of breath

Another symptom of coronary artery disease is short breath, fatigue and a feeling of exertion.

3. Heart attack

Complete blockage of the coronary artery results in a heart attack that is a prominent symptom of coronary artery disease. A person may feel heavy pressure in the chest, pain in the shoulder or arm, sweating etc. prior to getting a heart attack.

Causes:

Coronary artery disease occurs when damage or injury is done to the inner layer of the coronary artery. This damage causes plaque, which are deposits made of fat, cholesterol and other cellular waste materials to accumulate near the damaged area of the artery. This process is known as atherosclerosis.

The various causes that result in coronary artery damage are listed below.

- Smoking
- High blood pressure
- Diabetes
- High cholesterol
- Obesity
- High stress
- Physical inactivity

Knowing Coronary Artery Disease - Symptoms and Causes

In addition to pumping blood to various organs, the heart also has its own blood supply, through which it receives its oxygen and nutrient supply. In patients with coronary artery disease and atherosclerosis, there is a narrowing of the blood vessels which reduces the amount of blood flow to the target organs, including the heart. 

When this happens in the heart, there is chest pain due to overexertion of the heart muscles. There could be two patterns to this chest pain. With regular exertion like exercise, there would be chest pain, and most patients are familiar with this pattern.

This is known as angina pectoris or stable angina. In some people or in some instances, chest pain occurs which is sudden and not of a predictable pattern. It could be related to extreme exertion or stress. This is known as unstable angina and can lead to heart attack and be life-threatening.

Stable angina or angina pectoris has a stable, predictable pattern which most patients get familiar with over a period of time and learn to manage. Read on to know more about the signs and symptoms and management techniques.

Signs and symptoms: Stable angina usually occurs after a round of physical exertion. The patient feels a feeling of tightness in the chest which feels like the chest being squeezed. The pain can gradually spread to the shoulder, arms and even the neck. The pain can also be induced by eating, exposure to cold, emotional stress. It lasts for about 15 minutes and is relieved by rest and sublingual nitroglycerin. The pain intensity does not change with position or coughing. In addition, the patient may also experience shortness of breath, fatigue, profuse sweating, nausea, and dizziness.
The patient may be able to detect signs on further testing including ECG, echocardiography and stress testing. Features like cardiomegaly, altered ejection fraction would be detected based on the severity of the disease.

Treatment: Immediate treatment to relieve the pain includes resting and sublingual nitroglycerin. On an ongoing basis, the treatment would include 3 approaches   lifestyle changes, medications, and surgery.

Lifestyle changes: Regular exercise, smoking cessation, reduced fat intake, reduced alcohol consumption, weight loss, and stress management are some lifestyle changes to be made to improve symptoms.
Medications: A number of medications would be used depending on patient s symptoms. Aspirin to prevent clotting, medications to control blood pressure and cholesterol and diabetes.
Surgery: In patients with advanced coronary artery disease, revascularization methods may be required, which includes angioplasty and coronary bypass.
In a person with known risk factors, it is advisable to have regular checkups so that the disease progression can be controlled and symptoms managed with minimal intervention.

Predictable Chest Pain Pattern - What Does It Indicate?

The term 'chest pain  is a very common term and is usually used in day to day life. Basically, chest pain refers to the pain that may generate in your chest, shoulder and can travel to your ribs, jaws and towards your arms. The feeling of the pain can be sharp or dull, depending on the severity of your condition and cause.

There can be several reasons behind chest pain. You need to conduct a few tests to examine the real cause of the chest pain. It is always advised by health experts to take the symptoms of chest pain very seriously in order to avoid any serious problem in the future. Most of the severe and life-threatening diseases behind chest pain involve lung and heart problems. People having serious heart problems often feel discomfort, followed by pain in their chest area.

Symptoms
Chest pain which is related to any heart disease such as heart attack usually has symptoms like:

Feeling of fullness and tightness in the chest region
Vomiting
Nausea
Burning or crushing pain, which travels from the chest to jaw, hands and back region.
Weakness
Breathing problem
Usually, it is very tough to distinguish whether the pain is associated with a heart problem or not. But generally chest pains which are not related to heart problems involves symptoms like

Sensation in your mouth
Problem in swallowing food
Pain that worsens when you cough
Burning sensation in your chest
Common causes of chest pain

Angina: Angina is a medical condition described as a feeling of discomfort or pain in the chest region. This situation occurs when your heart muscles don't receive blood, which contains rich oxygen. Angina is a symptom of Coronary Heart Disease (CHD). The pain can take place in your shoulder, jaw, neck and arms also.
Lung problems: People with lung disorders can encounter various types of chest pains. But some common causes are:
Pleurisy: It is a type of medical condition, which occurs due to inflammation of the lining of chest and lungs. Due to this, you feel a sharp pain at the time of breathing, coughing or sneezing.
Pneumonia: It is a type of lung infection, which causes chest pain.
Pneumothorax: It is a type of lung disorder, which occurs when a portion of your chest gets collapsed.
Asthma: It is a type of condition, which occurs due to shortness of breath and causes chest pain while coughing, sneezing and breathing.
Gastrointestinal problem: Gastroesophageal reflux disease (GERD) is also a common reason for chest pain such as burning sensation in your heart.
Other causes of chest pain: There are several other reasons of chest pain such as muscle strain, ribs injury, shingles, anxiety and panic attacks. It is always important to visit a physician whenever you encounter any of such chest pain symptoms.

How Chest Pain Related to Heart Problems?

Causes and Symptoms of Renal Hypertension

High blood pressure is characterized by an increased force that the blood exerts on the blood vessels when it moves through the body. Renal hypertension is a blood pressure disorder where the arteries that carry blood to the kidneys become narrow, as a result of which the blood pressure through these vessels increases.

Causes

It is caused when the arteries that supply blood to the kidney get narrow or get blocked. This can cause the kidney to release specific hormones that signal the body to retain water and sodium. This can put additional pressure on the blood vessels which leads to increased blood pressure. It can also be caused by atherosclerosis which is characterized by hardening of the arteries. Improper development of the arteries can also lead to renal hypertension.

Symptoms

The symptoms of renal hypertension are:

Feeling confused
Blurred vision
Regular headaches
Bleeding from the nose
Gradual decline in kidney function
Possible long-term damage to the kidney
Feeling lethargic and drowsy
Loss of appetite
Dryness in skin
Muscle cramps
Breathing difficulties

Treatments

The diagnostic procedure for this disorder consists of blood, urine, doppler ultrasound and CT angiography or MR angiography tests. Treatments for this disorder usually include medications to ease blood pressure. Preventive measures include modifications in lifestyle such as following a proper diet, limiting smoking, restricting sodium or salt in the diet and following an exercise regimen. Steps should also be taken to reduce stress. Yoga and meditation are highly beneficial to control the condition. Sometimes intervention is needed in the form of PTRA and stenting.

High Blood Pressure and Kidney Disease - Causes and Symptoms!

Cholesterol is a vital component, which helps the body to make healthy cells. This wax like component is found in the lipid of the blood. An increased cholesterol count elevates the risk of heart diseases in a person. It thickens the vessels of the arteries resulting in less oxygen flow in the heart. This, in turn, increases the chances of a stroke. High cholesterol can happen from lifestyle habits and inheritance. It is completely treatable and preventable.

What causes high cholesterol?
The blood carries the cholesterol which is attached to the proteins. The combination of cholesterol and protein is known as the lipoprotein. Primarily there are two different kinds of cholesterol that the lipoprotein carries:

    Low-density lipoprotein: LDL is the bad guy that carries all kinds of cholesterol present in the body. It eventually rests on the walls of the arteries, making it narrow and hard.
    High-density lipoprotein: This is the good guy which scans the excess cholesterol and take them back to the liver.

Ideally, the body should have low LDL and high HDL. But often the reverse happens, resulting in high cholesterol and cardiac diseases. Factors such as unhealthy diet, inactivity for most of the day and obesity is responsible for the same. Even the genetic set up can play a hand in a high count of LDL in the body. There is nothing that can be done in this case except to seek medical help.

6 factors that put you at risk:

    Poor diet: Cholesterol levels are dramatically increased when baked products and saturated fats are consumed in an excess amount. Other high cholesterol food products include dairy products, processed fats and red meat. Refraining from this food items will drastically reduce the chances of getting high cholesterol in the body.
    Obesity: Obesity results from too much of fat storage in the body. It not only fatigues a person faster, but puts a person at high risk of getting cholesterol. The body mass index should be always lesser than 30 to abstain the risk of cholesterol.
    Waist circumference: A waist circumference of more than 40 inches in men and 35 inches in women can increase the risk of cholesterol.
    Diabetes: This is one of the major causes of high cholesterol. It not only damages the artery lining, but results in higher LDL and lower HDL.
    Less workout: Leading a life which is devoid of exercise and jogging can increase the chances of getting high cholesterol. Exercise boost HDL count in the body and mitigates the risk of low HDL.
    Smoking: The blood vessel walls get damaged with smoking. The blood vessels start accumulating fatty acids thereby increasing the chances of getting high cholesterol.

What Causes High Cholesterol? 6 Factors That Put You at Risk

Heart attack, also known as myocardial infarction, is a severe condition where death of the heart muscle occurs because of the loss of blood supply. The blood loss usually happens because of the blockage of a coronary artery. Due to electrical instability, ventricular fibrillation is caused. Heart attacks may result in permanent brain damage or even death.

Symptoms of heart attack
There are many early symptoms and signs of heart attack, which should be recognized. Symptoms of heart attack vary from person to person. Here is a list of the primary heart attack symptoms:

Chest pain and discomfort:
Chest pain is the basic symptom of a heart attack and occurs in different forms. The chest pain has a pressure, fullness and squeezing sensation and starts from the center of the chest. The pain may go away and re-occur and may spread down to other limbs of the body.
Headache, toothache:
The chest pain occurring due to a heart attack spreads all over the body and the jaw. Even the back and head are affected. Sometimes pain in these regions is present while chest pain is absent.
Shortness of breath:
A gasping sensation or feeling shortness of breath is another common sign of a heart attack. Such breathing difficulty is called dyspnea. The shortness of breath occurs before or during the chest pain.
Nausea and vomiting:
The feeling of nausea or sickness in the stomach is another possible symptom. It is accompanied by belching or burping and sometimes, the heart attack is associated with a feeling of indigestion. Nausea is more common in women. Vomiting also occurs alongside nausea.
General epigastric discomfort:
In several cases, patients describe the pain of a heart attack as stomach pain. The pain is heavy and uncomfortable and persists for several minutes.
Sweating:
Perspiration or sweating occurs during a heart attack and the patient experiences cold sweat in avid amounts.

Emergency treatment for heart attack-
A person who has a heart attack should be rushed to a hospital.
Several tests are carried out to detect the cause of the attack. A 12 lead ekg is carried out to supervise electrical activity within the heart and detect the damaged areas.
Blood tests are undertaken to check enzymes and in certain cases, cardiac catheterization is required where pictures of the blood vessels are examined.
Emergency medicines are given to the patient to stop the formation of blood clots and include aspirin, heparin and other drugs. Other medicines are given for thrombolytic therapy, which dissolve already formed blood clots. They work to reduce the heart damage. Nitrates are also used.

A heart attack is a severe condition and must be attended to immediately. Emergency treatment procedures are essential to save the life of an affected person.
