Atherosclerosis is a disease in which plaque builds up inside the arteries, limiting blood flow. It is caused by chronic inflammation and is the leading cause of heart attacks and strokes. Risk factors include high cholesterol, hypertension, smoking, and diabetes. As plaque builds up over decades, it can restrict blood flow and cause chest pain, heart attack, or stroke. Diagnosis involves medical tests like ECG, blood tests, and imaging. Treatment focuses on lifestyle changes and medications to control risk factors and prevent further progression of disease.

4. • Lifestyles of populations across the world
have changed dramatically in the 20th
century. These changes (collectively
termed as epidemiological transition)
have been brought about by a number of
developments in science and technology
that now affect every facet of human
existence.
• Most human societies have moved from
agrarian diets and active lives to fast
foods and sedentary habits. Combined
with increasing tobacco use, these changes
have fuelled the epidemic of obesity,
diabetes, hypertension, dyslipidemia and
cardiovascular diseases (CVD).
6. • Coronary heart disease (CHD) is the most
common form of Cardiovascular diseases
(CVD) and caused by atherosclerosis in the
large and medium sized arteries that supply
the heart muscle with oxygen and nutrients.
• Also called as coronary artery disease (CAD)
• In developed nations the rise in the burden of
CVD occurred over several decades due to a
long period of epidemiological transition.
• In India, perhaps because of the rapid pace of
economic development, epidemiological
changes have spanned a much shorter time. As
a consequence, cardiovascular disease (CVD)
has emerged as the leading cause of death all
over India, with coronary heart disease (CHD)
affecting Indians at least 5-6 years earlier than
their western counterparts.

9. • Atherosclerosis (also known as arteriosclerotic
vascular disease or ASVD) is a special form of
arteriosclerosis in which an artery wall thickens
as a result of invasion and accumulation of
WBCs.
• Atherosclerosis is a syndrome affecting arterial
blood vessels due to a chronic inflammatory
response of WBCs in the walls of arteries. This
is promoted by low-density lipoproteins (LDL,
plasma proteins that carry cholesterol and
triglycerides) without adequate removal of fats
and cholesterol from the macrophages by
functional high-density lipoproteins (HDL). It is
commonly referred to as a "hardening" or
furring of the arteries. It is caused by the
formation of multiple atheromatous plaques
within the arteries.
• Atherosclerosis is a chronic disease that remains
asymptomatic for decades.
• The incidence of atherosclerosis is difficult to
determine since it mainly an asymptomatic
condition. The pathological process begins in
childhood and continues throughout the life. In
the United Kingdom, the frequency of clinical
manifestations of atherosclerosis is high,
especially in the West of Scotland.
20. • Cardiac remodeling may be defined as genome expression, molecular, cellular and interstitial
changes that are manifested clinically as changes in size, shape and function of the heart after
cardiac injury.
• It occurs after myocardial infarction, pressure overload (aortic stenosis, hypertension),
inflammatory heart muscle (myocarditis), idiopathic dilated cardiomyopathy or volume
overload (valvular regurgitation).
• The process of cardiac modeling is mainly influenced by hemodynamic load and
neurohormonal activation.
• The myocyte is the major cardiac cell involved in the remodeling process. Other components
involved include the interstitium, fibroblasts, collagen and coronary vasculture; relevant
processes also include ischemia, cell necrosis and apoptosis.

28. Cardiac prudent diet
Diet should be low in saturated fats, Trans fats as well as cholesterol.
20kcal/kg body weight is recommended for obese patients in bed and 25kcal/kg body
weight for those near ideal body weight.
Fats should be 15-20% of total calories
Carbohydrate intake should be limited to 60 per cent of total energy in patients with
metabolic syndrome.
Normal allowances of protein are recommended (1gram/kg body weight).
Mega doses of niacin have been known to be an effective treatment of dyslipdemia
Diet should be rich in dietary fibre, MUFA and PUFA.
Vitamin B6, B12, and folic acid supplementation decreases the risk of cardiovascular
disease related to homocysteine risk factor.
200-300mg of Vitamin C reduces cholesterol
A restriction of sodium of 1600-2300 mg is satisfactory among patients with
atherosclerosis
Potassium helps to maintain cell fluid balance and plays a role in muscle contraction.
Low levels of this mineral have been associated with high blood pressure.
Magnesium helps muscles relax, affects the muscle tone of blood vessels and keeps
heart rhythm steady.
Low glycaemic index diets may preserve HDL cholesterol and thus have a potentially
positive effect in reducing CHD risk.
29. • A functional food is any food that has a
positive effect on a person’s health,
physical performance or state of mind.
• Reduces the risk of chronic diseases and
physiological benefits when eaten on a
regular basis in adequate amounts.
• Foods rich in antioxidants,
hypocholesterolemic agents and
phytochemicals protect from Coronary
Heart diseases.
• Antioxidants including Vitamin C, E β-
carotene have potential health benefits of
reducing cardiovascular diseases.

Atherosclerosis is a disease in which plaque builds up inside your arteries. Over
time, plaque hardens and narrows your arteries, limiting the flow of oxygen-rich
blood. This can lead to serious problems. Atherosclerosis is a disease in which
plaque builds up inside your arteries. Over time, plaque hardens and narrows
your arteries, limiting the flow of oxygen-rich blood. This can lead to serious
problems Atherosclerosis usually doesn't cause symptoms until it severely narrows
or totally blocks an artery. Many people don't know they have the disease until
they have a medical emergency. When symptoms do happen, they are specific to
the arteries affected by atherosclerosis. A physical examination, imaging, and other
diagnostic tests can tell if the patient have this disease. Treatments include
medicines, and medical procedures or surgery. Lifestyle changes can also help.
These include following a healthy diet, getting regular exercise, maintaining a
healthy weight, and quitting smoking.
