Ectasia (), also called ectasis (), is dilation or distention of a tubular structure, either normal or pathophysiologic but usually the latter (except in atelectasis, where absence of ectasis is the problem). Specific conditions
Bronchiectasis, chronic dilatation of the bronchi
Duct ectasia of breast, a dilated milk duct. Duct ectasia syndrome is a synonym for nonpuerperal (unrelated to pregnancy and breastfeeding) mastitis. Dural ectasia, dilation of the dural sac surrounding the spinal cord, usually in the very low back. Pyelectasis, dilation of a part of the kidney, most frequently seen in prenatal ultrasounds. It usually resolves on its own. Rete tubular ectasia, dilation of tubular structures in the testicles. It is usually found in older men. Acral arteriolar ectasia
Corneal ectasia (secondary keratoconus), a bulging of the cornea.Vascular ectasiasMost broadly, any abnormal dilatation of a blood vessel, including aneurysms
Annuloaortic ectasia, dilation of the aorta. It can be associated with Marfan syndrome. Dolichoectasias, weakening of arteries, usually caused by high blood pressure. Intracranial dolichoectasias, dilation of arteries inside the head. Gastric antral vascular ectasia, dilation of small blood vessels in the last part of the stomach. Telangiectasias are small dilated blood vessels found anywhere on the body, but commonly seen on the face around the nose, cheeks, and chin. Venous ectasia, dilation of veins or venules, such as:
Chronic venous insufficiency, often in the leg
Jugular vein ectasia, in the jugular veins returning blood from the head

Not enough sleep also raises the risk of high blood pressure. Adults need about 7–9 hours of sleep. Sleep apnea is also a major risk as it causes breathing to stop briefly, which can put stress on the body which can raise the risk of heart disease.Most guidelines recommend combining preventive strategies. There is some evidence that interventions aiming to reduce more than one cardiovascular risk factor may have beneficial effects on blood pressure, body mass index and waist circumference; however, evidence was limited and the authors were unable to draw firm conclusions on the effects on cardiovascular events and mortality.There is additional evidence to suggest that providing people with a cardiovascular disease risk score may reduce risk factors by a small amount compared to usual care. However, there was some uncertainty as to whether providing these scores had any effect on cardiovascular disease events. It is unclear whether or not dental care in those with periodontitis affects their risk of cardiovascular disease. Diet
A diet high in fruits and vegetables decreases the risk of cardiovascular disease and death.A 2021 review found that plant-based diets can provide a risk reduction for CVD if a healthy plant-based diet is consumed. Unhealthy plant-based diets do not provide benefits over diets including meat. A similar meta-analysis and systematic review also looked into dietary patterns and found "that diets lower in animal foods and unhealthy plant foods, and higher in healthy plant foods are beneficial for CVD prevention".
