Definition: Small vessel disease is a condition in which the small arteries in the heart become narrowed. Small vessel disease causes signs and symptoms of heart disease, such as chest pain (angina). Small vessel disease is sometimes called coronary microvascular disease or small vessel heart disease. It's usually diagnosed after a doctor checks for blockages in the main arteries of the heart but finds little or no narrowing in the large vessels, even though your symptoms persist.
Symptoms: Chest pain, squeezing or discomfort, Chest pain associated with discomfort in your left arm or jaw, Chest pain that worsens with daily activities and at times of emotional stress, Neck, shoulder, upper back or abdominal discomfort, Shortness of breath, Unusual fatigue, A loss of energy, Trouble sleeping.
Statistics: Cognitive performance of the SIVD group was inferior to that of the normal control group throughout all domains. As compared to the other stroke patients, the SIVD group performed significantly worse in tests measuring executive functions and delayed memory recall. Adjusting for depression had no effect on these results. Instead, after controlling for medial temporal lobe atrophy, the differences disappeared for delayed memory but remained significant for executive functions.
