MEDICINE & TECHNOLOGYOver the last century, technologies in the medicalfield have been advancing to the point where infectionsand diseases do not concern people as much as they onceuse to. Diseases such as small pox and polio havevirtually disappeared. As we continue to pursue thesetechnological advances, many otherdiseases, illnesses, and life threatening medicalconcerns may one day be eradicated.
WHAT IS HEART DISEASE? Your heart is a muscle that gets energy from blood carrying oxygen and nutrients. Having a constant supply of blood keeps your heart working properly. Most people think of heart disease as one condition. But in fact, heart disease is a group of conditions affecting the structure and functions of the heart and has many root causes. (Heart & Stroke)
o In Canada, every 7 minutes someone dies from heart disease or stroke o Responsible for an estimated 29% of deaths in Canada (28% of all boys and 29% of all girls) o Leading cause of hospitalization in Canada o Cost Canada about 20.9 billion dollars each year in services and medical cost o Nine in 10 Canadians have at least one risk factor for heart disease or stroke (smoking, alcohol, physical inactivity, obesity, high blood pressure, high blood cholesterol, diabetes) (Heart & Stroke) o Less than 5% of people who have(Heart and cardiac arrest outside of aStroke)
THE HEART & OUR TECHNOLOGYThe heart is one of our body’s most vital organs andmuscle. As our society encounters new illnesses anddiseases that danger the heart, we are scrambling tofind new innovative technologies to prevent and ‘fix’these medical issues.In the last decade technology has rapidly advanced inthe medical field. We continue to explore the humanbody and all its wonders and whilst doingso, technology is growing alongside these learningcurves.Society is fighting tooth and nail to save the lives ofindividuals suffering from heart disease. As the amountof equipment and procedures grow, we are saving livesas we move towards the goals of complete heart diseaseprevention.
A LOOK INSIDE THESE LIFE-SAVING TECHNOLOGIES 1. THE DEFIBRILLATOR 2. THE PACEMAKER 3. THE EKG 4. THE HEART TRANSPLANT
THE DEFIBRILLATORo The defibrillator is a device that delivers an electrical shock to people suffering from cardiac arrhythmias, ventricular fibrillation and pulseless ventricular tachycardia. The shock revives the hearts sinoatrial node (responsible for the hearts contractions).o For every 1 minute delay in defibrillation, the survival rate of a cardiac arrest victim decreases by 7% to 10% (What is a Defibrillator)
THE PACEMAKER o Pacemakers are an artificial sinoartial node(SA)responsible for keeping the heart from beating too slow. Some pacemakers are temporary while others may be permanent. o The pacemaker is inserted to prevent heart failure by maintaining the natural rhythms of the organ.
THE EKGo Electrocardiographyo The EKG is a device that analyzes and interprets the electrical patterns of the hearto This piece of equipment is utilized by health care professionals to understand a patients cardiovascular health.o This is the initial test conducted on an individual who is suspected of having heart problems (i.e. (J,Dwyer) heart attack)
THE HEART TRANSPLANT Province Number of transplants British 22 Columbia Alberta 33 Ontario 68 Québec 39 Nova 5 Scotia TOTAL 167 o The heart transplant is a procedure performed on individuals with end-stage heart diseases. o Amazingly, a heart from a donor can replace a(Heart and damaged heart; saving lives.Stroke)
Heart disease is the one of the leading causes of death in the world and although the death rate is currently at an all time high, there is no doubt that the statistics are much lower than they once were. The amount of research and technology that is being addressed to heart disease will unquestionably savelived and drastically reduce the number of individuals suffering from this catastrophic disease.

The only con related tomedical advances may justbe the exponential costs. And yes, technology is expensive.But, can we really put a price on someone’s life?
