Heart Attack: Heart attack is when the blood vessels become blocked and fails to supply oxygen to heart. It’s also called as Myocardial Infarction.

Causes:

Most heart attacks are caused by a blockage of coronary arteries. Blood may form clot in arteries. The coronary arteries supply blood and oxygen to the heart. If the blood flow is blocked, the heart starves for oxygen and heart cells die.

In atherosclerosis, plaque builds up in the walls of your coronary arteries. This plaque is made up of cholesterol and other cells. A heart attack can occur as a result of the following:

· The slow build up of plaque may almost block one of your coronary arteries. A heart attack may occur if not enough oxygen-containing blood can flow through this blockage. This is more likely to happen when you are exercising.

· The plaque itself develops cracks (fissures) or tears. Blood platelets stick to these tears and form a blood clot (thrombus). A heart attack can occur if this blood clot completely blocks the passage of oxygen-rich blood to the heart. This is the most common cause.

Symptoms:

Chest pain is a major symptom of heart attack. You may feel the pain in only one part of your body, or it may move from your chest to your arms, shoulder, neck, teeth, jaw, belly area, or back.

The pain can be severe or mild. It can feel like:

· A tight band around the chest

· Bad indigestion

· Something heavy sitting on your chest

· Squeezing or heavy pressure

The pain usually lasts longer than 20 minutes. Rest and a medicine called nitro-glycerine may not completely relieve the pain of a heart attack. Symptoms may also go away and come back.

Other symptoms of a heart attack include Anxiety, Cough, Fainting, Light-headedness, Dizziness, Shortness of breath, Sweating

Some people (the elderly, people with diabetes, and women) may have little or no chest pain. Or, they may experience unusual symptoms (shortness of breath, fatigue, weakness). It’s called "silent heart attack".

Recession in pharmaceutical jobs in Canada

It has shown heavy recession in Pharmaceutical jobs in Canada in second half of 2010. Around 3600 jobs were lost in last year. Pharmaceutical manufacturing in Canada, and other established markets, has been hit by recession, emerging market competition and industry-specific challenges. Lay offs and closures followed and, although there has been some market improvement, recovery has been slow.

“The recession ended more than a year ago, but the global recovery has been slow”, said Michael Burt, associate director, Industrial Economic Trends at the Conference Board of Canada.

Today recession is at it's high level that it will take several years to recover the manufacturing industry of Canada including Pharmaceutical industry. it was said that the recession has been recovered but it has not been recovered totally.

Vancouver: Canada's manufacturing companies need more customers to sell the products.

Canadian pharmaceutical profits are expected to increase slightly in 2011 but industry pressures, such as emerging market competition and governmental fiscal restraint, will continue to restrict growth.

Despite these challenges the report says the fundamentals of the pharmaceutical industry remain solid because of demand from aging populations. Innovative approaches will be needed for Canadian companies to maintain a share of this market.

“One way for companies to improve operational efficiency and product development is to make innovation an integral part of their strategies. As an example, managers need to promote innovative thinking at all levels of their organisations”, said Nycz.
