A normally functioning circulatory system is vital for our survival . We have about 6000 ml of blood, circulating all over the body in an approximate time of 15-20 seconds.The pressure at which this blood moves across the body is called the blood pressure . Hypertension or simply , high blood pressure is an undesirable hemodynamic [...]

Angina pectoris , classically occur on exertion and gets relieved on rest .This is called typical chronic stable angina as described by Heberden (CSA ) . Unstable angina(UA), the term originally described by Noble O Fowler in early 1970s. ( Also being referred as intermediate coronary syndrome , preinfarction angina etc).The definition for unstable angina has evolved over the years and currently refers to .

During CABG arterial grafts are always preferred over venous grafts , for the simple reason the grafted vessel has to carry arterial blood and not the venous blood. Saphenous veins are tuned to carry venous blood at low pressure.The mean coronary arterial pressure is around 40mmhg and this will damage the saphenous venous endothelium more quickly. [...]
Great papers in cardiology

This is a hemodynamic concept paper by Libanoff in 1968 published in circulation.This paper elegantly proved that the rate of fall of pressure across the mitral valve will predict the mitral valve orifice. This key paper formed the foundation on which Liv hatle developed the echocardiographic pressure half time .This pressure half time derived [...]

Hypertension is considered a major cardiovascular risk factor.Hypertension can have multiple physiological and pathological effects on heart . The common response to raised arterial pressure is the hypertrophy of the left ventricle ( LVH). This can increase the risk of heart failure in few ( Mainly diastolic failure) It is a leading cause for stroke and less often [...]
