If you have a blocked artery within your
heart, you may be suffering from coronary artery disease (CAD). This disease is
caused by the build-up of cholesterol and fatty plaques within the arteries, a
condition referred to as atherosclerosis.
Atherosclerosis can interfere with the blood flow to
the heart by causing narrowing or blockage of the arteries. If the heart does
not receive enough oxygenated blood, it will not function normally, which can
lead to a heart attack. People with CAD can develop signs that indicate an
artery within the heart is blocked.
Angina
Angina is the most common symptom of a blocked artery
in people with CAD. People with angina typically report experiencing discomfort
or pain within the center of the chest. This pain can sometimes be described as
a sensation of heaviness, numbness, tightness, aching or burning within the
chest. Chest pain can also spread to other regions of the body if you develop a
blocked artery. Your chest pain can radiate into the arms, back, stomach, neck
or jaw. If you develop symptoms of angina, seek emergency medical care immediately
because this condition is also a sign of a heart attack.
Difficulty Breathing
If you develop a blocked artery within the heart, the
National Heart Lung and Blood Institute explains that breathing difficulties
can also occur. If you experience shortness of breath, walking up a flight of
stairs or performing normal daily activities can be difficult. If your heart
does not receive an adequate supply of blood, fluid can begin to build up
within your lungs and cause significant breathing problems. Seek emergency
medical care if you have breathing difficulties because this is also a symptom
of heart failure and heart attack.
Nausea
Certain people who develop a blockage within an artery
of the heart experience nausea as a consequence of this condition. Additional
gastrointestinal symptoms such as abdominal pain or vomiting can also occur in some
people.
Dizziness
A blocked artery within the heart prevents oxygenated
blood from reaching the brain. If this occurs, dizziness, lightheadedness,
fainting or loss of consciousness can occur in certain people. Extreme weakness
or anxiety can also be a sign of a blocked artery in certain instances. If you
develop any of these symptoms, seek emergency medical care as soon as possible.
Irregular Heartbeat
A rapid or abnormal heartbeat could be an indication
that you have a blocked artery within your heart. If your heart is not
receiving enough blood due to the blockage, it will start pumping faster to try
to bring more blood into the heart. A rapid heart rate could also cause you to
experience dizziness or chest pain. Contact your doctor if you notice a change
in your heart rate.
