ischemic heart diseasePRESENTATIONS OF ischemic heart disease(IHD). Read more ... » (IHO) is a disease of the heart due to a deficiency of supply of blood, oxygen and nutrients to the heart.
Ischemic heart disease occurs when there is imbalance between supply (of blood, oxygen, nutrients) and demand (increased demand, less supply).

- Collaterals do not develop in sudden occlusion of the coronary artery.
- Coronary blood supply is obstructed by atheroma, thrombus, thromboemboli, .
- When there is gradually progressive occlusion of the coronary arteries then collaterals develop which maintain the perfusion of the heart.
- If the cross-sectional area of coronary artery is reduced to 750/0, then at the time of increased demand, the blood flow cannot increase appropriately It means there is significant coronary artey obstruction, and such patients are usually symptomatic.
- At 800/0 reduction of the cross sectional areal the
- blood flow at rest is also compromised. Such
- patients are greatly handicapped, and are unable to carry out even routine activities without discomfort ..
