Clogged Arteries- Signs & Symptoms


Arteries introduction

Arteries are blood vessels that carry blood rich in oxygen throughout your body. They go to your brain as well as to the tips of your toes. Healthy arteries have smooth inner walls and blood flows through them easily. Some people, however, develop clogged arteries.


What are clogged arteries?

Clogged arteries result from a buildup of a substance called plaque on the inner walls of the arteries. Arterial plaque can reduce blood flow or, in some instances, block it altogether. Clogged arteries greatly increase the likelihood of heart attack, stroke, and even death. Because of these dangers, it is important to be aware, no matter how old you are, of the causes of artery plaque and treatment strategies to prevent serious consequences.

What causes clogged arteries? 

Plaque that accumulates on the inner walls of your arteries is made from various substances that circulate in your blood. These include calcium, fat, cholesterol, cellular waste, and fibrin, a material involved in blood clotting. In response to plaque buildup, cells in your artery walls multiply and secrete additional substances that can worsen the state of clogged arteries. As plaque deposits grow, a condition called atherosclerosis results. This condition causes the arteries to narrow and harden.


What are the risk factors of clogged arteries? 

High Cholesterol: If you have high ''bad'' cholesterol and low ''good'' cholesterol then your risk increases. High levels of ''bad'' cholesterol, or low-density lipoprotein (LDL), are major contributors to arterial plaque formation. But that doesn’t tell the whole story. Everyone also has ''good'' cholesterol, or high-density lipoprotein (HDL), circulating in the blood. HDL is believed to remove some of the bad cholesterol from plaque in clogged arteries and transport it back to the liver, where it is eliminated.

High Blood Pressure: Having high blood pressure increases the rate at which arterial plaque builds up. It also hastens the hardening of clogged arteries.

Cigarette smoke: Cigarette smoke seems to increase the rate of atherosclerosis in the arteries of the heart, legs, and the aorta -- the largest artery in the body.

Diabetes: or elevated circulating blood sugar, is also a major culprit. Even people who have elevated sugars not yet at the level of diabetes, such as seen in metabolic syndrome, also have increased risk of plaque formation. 

• Other risk factors include family history, stress, sedentary lifestyle and obesity. Knowing your family history is critical.

 


What are the dangers of clogged arteries? 

It depends on where arterial plaque accumulates. Clogged arteries in different parts of the body can lead to multiple medical conditions, including:

Coronary artery disease: When plaque accumulates in the arteries carrying blood to the heart, it results in coronary artery disease, or heart disease. Coronary artery disease can cause chest pain or shortness of breath. This condition can lead to heart attacks. 

Carotid artery disease: The carotid arteries run up either side of your neck. They supply oxygen to your brain. The accumulation of arterial plaque in the carotid arteries can lead to stroke.

Peripheral artery disease: If plaque builds up in the blood vessels that carry blood to your legs, it can reduce the amount of oxygen delivered. The reduced blood flow can cause you to experience pain, numbness, or serious infection in your legs and feet.


What are the symptoms of clogged arteries? 

The first symptom, chest pain, is also called angina. It may result from reduced blood flow to the heart. That reduced blood flow is caused by plaque in the arteries leading to the heart. hen the artery is blocked by 70% or more, the buildup of arterial plaque may cause symptoms that include: 

• Chest pain

• Shortness of breath

• Heart palpitations

• Weakness or dizziness

• Nausea

• Sweating

What are the symptoms of clogged arteries in carotid artery disease? 

Clogged arteries in carotid artery disease may cause stroke precursors known as transient ischemic attacks, or TIAs. TIAs may produce the following symptoms:

• Sensation of weakness or numbness on one side of your body

• Inability to move an arm or a leg

• Loss of vision on one side only

• Slurring of words


What are the symptoms of clogged arteries in peripheral artery disease? 

• Leg pain

• Delayed healing of injuries to the feet

• Cold feet

• Gangrene


How is clogged arteries diagnosed? 

Your doctor will determine which tests to prescribe based on your symptoms and medical history. The tests may include:

• Cholesterol screening

• Chest X-ray

• CT scan

• Ultrasound

• Echocardiogram and/or cardiac stress test

• Electrocardiogram

• MRI or PET scanning

• Angiogram


Clogged Arteries Prevention Tips 

Lifestyle changes. A healthy lifestyle is essential for the management of arterial plaque and treatment of clogged arteries. This includes:

  • Eating a diet low in saturated fats and cholesterol, with less sugars and simple carbohydrates, and rich in fruits and vegetables
  • Maintaining a healthy body weight
  • Not smoking
  • Exercising regularly
  • Managing stress levels
  • Keeping blood pressure and cholesterol down
  • Maintaining low blood sugars
