About Cardiology and Vascular Disease
The heart and blood vessels are responsible for carrying
oxygen, nutrients, and waste products around the body to where
they are to be used, or disposed of. The circulation of the blood
is driven by the heart's action, so that heart disease has
far-reaching effects on the body's well being.
Arterial disorders are dominated by atherosclerosis, a
condition in which the inside wall of the artery becomes thicker
and less elastic, and blood flow is reduced. Cholesterol and
similar substances called lipoproteins attach themselves to the
linings of the arteries, where they gradually thicken into a
substance called plaque. A heart attack (myocardial infarction,
or MI), or stroke may result.
Disorders of the venous side of the circulation include
varicose veins and deep venous thrombosis; the latter may be
responsible for a pulmonary embolism (a blood clot that breaks
off and lodges in the veins of the lung).
Cardiology and Vascular Diseases Clinical Trials at Novartis
Novartis is developing new drugs in several important areas of
cardiovascular disease. Some of these include:
High blood pressure (hypertension)
This condition usually causes no symptoms, unless the pressure
gets extremely high; it's therefore often called the "silent
killer". Middle-aged Americans face a 90% chance of developing
high blood pressure at some time during the rest of their lives.
About half of those who already have hypertension are not being
treated, and a quarter of them are being treated inadequately.
Over time the elevated pressure causes damage to the blood
vessels and to the organs the vessels supply with blood. This
can result in stroke, heart attack, kidney failure, heart failure
and damage to the eye, called retinopathy.
Heart failure
This occurs when the heart can't pump out enough blood to meet
the needs of the body. Any form of heart disease (coronary artery
disease, a heart attack, heart valve disease) as well as severe
high blood pressure may lead to heart failure, which results in a
reduced ability to exercise and, in severe cases, interferes with
daily activities.
Coronary artery disease
Atherosclerosis of the coronary arteries (the arteries supplying
the heart muscle) can lead to angina, or a heart attack. Lifestyle
changes (exercise, nutritional changes, weight control) can
reduce or slow the atherosclerotic changes responsible for
coronary artery disease. New medications that may assist with
control of underlying high blood pressure, high blood sugar,
and/or dyslipidemia are being investigated.
Dyslipidemia
Although cholesterol gets the most attention as a major risk
factor for coronary artery disease, there are several measurable
blood lipids that can be present in abnormal amounts in
dyslipidemia - total cholesterol, low-density lipoprotein (LDL)
cholesterol, high-density lipoprotein (HDL) cholesterol, and
triglycerides are the main ones. Elevation of any (or, in the
case of HDL- cholesterol, reduction) represents increased
cardiovascular risk. Newer therapies targeting the specific
changes requiring correction are being investigated.
