Sleeping problems, unusual fatigue, chest pain with discomfort in the left jaw or arm and shortness of breath are symptoms of chronic small vessel ischemia, according to Mayo Clinic. Patients with coronary artery disease with stents and angioplasty are more prone to small vessel disease.
A patient with chest pain and symptoms such as sweating, nausea, difficulty breathing, dizziness and unbearable pain from the chest to the arms or neck should consult a doctor immediately, recommends Mayo Clinic. Symptoms such as abdominal pain and fatigue are common to other diseases so it may be difficult to determine a diagnosis. In the case of chronic chest pain, a patient should seek medical assistance.
While the function of the large arteries is to pump blood via the heart, the small vessels expand when one vessel is active and contract when one vessel is at rest. When the small vessels narrow, they become difficult to stretch when one is active. This leads to an inadequate oxygen supply in the body. Doctors refer to this condition as endothelial dysfunction, explains Mayo Clinic. This problem makes the small blood vessels even smaller when one is active or under emotional turmoil. Lack of proper oxygenation leads to breathing problems and other symptoms.
