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: Out of 572 included patients, 171 (29.9%) were diagnosed with CIND-mild, 197 (34.4%) with CIND-moderate, and 28 (4.9%) with dementia. Risk factors related to a smaller cortical thickness were increased age, male sex, Malay ethnicity, higher blood glucose, and body mass index levels and presence of lacunar infarcts on MRI. Smaller cortical thickness was associated with CIND moderate/dementia [odds ratio (OR) per standard deviation (SD) decrease: 1.70; 95% confidence interval (CI): 1.19–2.44, P = 0.004] and with composite Z-score reflecting global cognitive functioning [mean difference per SD decrease: −0.094; 95% CI: −0.159; −0.030, P = 0.004].
