Question: What are the symptoms of Atherosclerosis ?
Answer: Atherosclerosis usually doesn't cause signs and symptoms until it severely narrows or totally blocks an artery. Many people don't know they have the disease until they have a medical emergency, such as a heart attack or stroke.
                
Some people may have signs and symptoms of the disease. Signs and symptoms will depend on which arteries are affected.
                
Coronary Arteries
                
The coronary arteries supply oxygen-rich blood to your heart. If plaque narrows or blocks these arteries (a disease called coronary heart disease, or CHD), a common symptom is angina. Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough oxygen-rich blood.
                
Angina may feel like pressure or squeezing in your chest. You also may feel it in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion. The pain tends to get worse with activity and go away with rest. Emotional stress also can trigger the pain.
                
Other symptoms of CHD are shortness of breath and arrhythmias (ah-RITH-me-ahs). Arrhythmias are problems with the rate or rhythm of the heartbeat.
                
Plaque also can form in the heart's smallest arteries. This disease is called coronary microvascular disease (MVD). Symptoms of coronary MVD include angina, shortness of breath, sleep problems, fatigue (tiredness), and lack of energy.
                
Carotid Arteries
                
The carotid arteries supply oxygen-rich blood to your brain. If plaque narrows or blocks these arteries (a disease called carotid artery disease), you may have symptoms of a stroke. These symptoms may include:
                
Sudden weakness
                
Paralysis (an inability to move) or numbness of the face, arms, or legs, especially on one side of the body
                
Confusion
                
Trouble speaking or understanding speech
                
Trouble seeing in one or both eyes
                
Problems breathing
                
Dizziness, trouble walking, loss of balance or coordination, and unexplained falls
                
Loss of consciousness
                
Sudden and severe headache
                
Peripheral Arteries
                
Plaque also can build up in the major arteries that supply oxygen-rich blood to the legs, arms, and pelvis (a disease calledperipheral artery disease).
                
If these major arteries are narrowed or blocked, you may have numbness, pain, and, sometimes, dangerous infections.
                
Renal Arteries
                
The renal arteries supply oxygen-rich blood to your kidneys. If plaque builds up in these arteries, you may develop chronic kidney disease. Over time, chronic kidney disease causes a slow loss of kidney function.
                
Early kidney disease often has no signs or symptoms. As the disease gets worse it can cause tiredness, changes in how you urinate (more often or less often), loss of appetite, nausea (feeling sick to the stomach), swelling in the hands or feet, itchiness or numbness, and trouble concentrating.
