Statistics
Although cardiovascular disease remains the leading cause of death in Canada,mortality rates have dropped significantly since the early 1950’s.
Cardiac Rehabilitation programs emphasize prevention strategies targeted at reducing the major risk factors associated with heart disease, lowering the risk of death by 20-25%.

The Heart and How It Works
• Hollow Muscular Organ • Size of a clenched fist • Located in the center of
the chest cavity behind the breast bone.
A pump with a big job to do!
![Page 6: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/6.jpg)
The heart pumps blood into the lungs to pick up oxygen
The blood returns to the heart and is then pumped into arteries and capillaries that carry blood rich in oxygen and nutrients to every cell of the body
The Heart and How It Works
![Page 7: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/7.jpg)
• The Heart as a muscle requires oxygen and nutrients and has its own network of 3 coronary arteries to feed the heart muscle
• These arteries curl around the surface of the heart and plunge into the muscle bed where they divide like branches of a tree to reach every fiber in the heart
Coronary Arteries
![Page 8: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/8.jpg)
Coronary Artery Disease
• A condition in which the arteries that supply the heart muscle with blood containing oxygen and nutrients become narrowed or blocked
• Fatty streaks line the inner blood vessel and build up into “plaques” small clumps of irregular shapes and sizes that project out from the wall of the artery causing the narrowing
![Page 9: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/9.jpg)
Signs And Symptoms… When arteries are narrowed the blood cannot
flow freely through them which reduces the supply of oxygen to the heart muscle
The heart sends out a signal or warning sign called angina *angina pectoris or “chest pain”
A tightness, a pressure, or a squeezing sensation in the middle of the chest
It may radiate into the neck, jaw, throat, elbows. It can present as shortness of breath or
heartburn.
![Page 10: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/10.jpg)
Angina
Angina is the signal of an imbalance in the demand of the heart muscle for oxygen
It is typically brought on with exertion and relieved with rest.
It is temporary and causes no muscle damageNitroglycerin sublingually relaxes the tone in the
walls of the arteries and improves the supply of oxygen rich blood to relieve the discomfort
![Page 11: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/11.jpg)
Factors that may cause Angina
5 “E’s” and Smoking: 1. Exercise2. Exertion3. Emotion4. Eating5. Exposure6. Smoking
![Page 12: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/12.jpg)
Heart AttackBlood flow through the coronary artery is
completely blocked, no blood and oxygen can get beyond the blocked artery and results in permanent damage to heart muscle
Onset not associated with activitySymptoms include:
Pressure, burning, tightness, heaviness or squeezing that persists for > 15 min and is not relieved with rest and nitroglycerin
Nausea, indigestion and/or vomiting Sweaty, clammy skin. Sense that something is very wrong
![Page 13: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/13.jpg)
After a Heart Attack: The Healing Process
It takes 6-8 weeks for the damaged muscle to form a scar
This strengthens the area of damage.New, smaller blood vessels can form to
supply the area around the damage with blood (collateral circulation).
![Page 14: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/14.jpg)

Cardiac Investigations
Cardiac Catheterization: A catheter is passed from femoral or brachial artery (groin or wrist) and dye injected into each coronary artery to determine narrowing or blockages and confirm diagnosis
![Page 17: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/17.jpg)

Risk Factors
![Page 24: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/24.jpg)
Risk Factors for Heart Disease

PressureHigh CholesterolDiabetesObesityPhysical InactivityStress
Non-Modifiable:AgeRaceGenderFamily History
![Page 25: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/25.jpg)
SmokingMost preventable cause of Coronary Artery Disease
Smoking increases the risk of developing coronary artery disease and also the risk of dying from it
Smoking increases the risk of in-stent blockageSmoking negatively affect bypass graftsNicotine contributes to build-up of fatty plaques
in your arteries, and increases the workload of the heart by increasing the heart rate and blood pressure
Carbon monoxide in smoke decreases the amount of oxygen being supplied to the heart.
![Page 26: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/26.jpg)
Managing Smoking
It is never too late to quit smokingHealth Benefits begin as soon as 20 minutes
from the time of the last cigaretteBlood pressure and heart rate return to normalBlood carbon monoxide levels to normal within
8-12 hrs, improving oxygen levels
Cardiac Rehab Program can Assist you in this process with group support sessions for “Preparing to Quit Smoking”
![Page 27: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/27.jpg)
High Blood Pressure
The target blood pressure we are aiming for is a blood pressure less than 140/90
Blood vessels are under more stress damaging the walls of the coronary arteries and making them more susceptible to plaque formation
![Page 28: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/28.jpg)
Managing Blood Pressure
Blood pressure will be monitored weekly prior to exercise sessions
If elevated over time 24 hour monitoring may be recommended to contribute to improved managementGroup Education and individualized counseling – Heart Healthy Diet
- Medication - Exercise
![Page 29: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/29.jpg)
High Cholesterol
An abnormal blood lipid profile has been a major risk factor for cardiovascular disease
Managing the levels to recommended target range has been shown to decrease cardiac events by slowing disease progression stabilizing the plaque and improving the function of the lining of the arteries
![Page 30: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/30.jpg)
Managing Cholesterol
Review of lipid profile Understand the numbersSet goals to lower your risk
Group education and individualized counseling Heart Healthy Diet Medication Exercise

Diabetes
In Type 2 diabetes the body either does not use the insulin it makes or it doesn’t make enough insulin causing high levels of glucose or “sugar” in the bloodstream.
Poorly controlled blood sugars accelerates the process of plaque build up causing damage to blood vessels and nerve endings
![Page 32: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/32.jpg)
Managing Diabetes
Reduce diabetes complications by keeping your blood sugar in your recommended target range and blood pressure<130/80
Monitor and record your blood glucose levels daily
Bring your glucometer to exercise sessions. <14 & >4 for safe exercise
Diabetes Education as required
![Page 33: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/33.jpg)
Managing Diabetes cont’d
Foot Care Rules:1. Never go barefoot, even indoors2. Wear shoes that fit properly. They
should be supportive, and should not rub or pinch
3. Wash and dry your feet (Especially between your toes) thoroughly
4. Wear fresh clean socks everyday5. Inspect your feet carefully every day6. Clean cuts or scratches with mild soap
and water
![Page 34: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/34.jpg)
Excess Body Weight
Excess body weight – adds strain on the heart
- increases the workload of the heart
Excess body weight also increases blood pressure and blood cholesterol
![Page 35: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/35.jpg)
Managing Ideal Body Weight
Studies have demonstrated significant heart health benefit associated with a 10% decrease in weight
Cardiac rehab offers counseling and support to assist you to achieve your target weight range Body Composition Analysis Heart Healthy nutrition education in group setting Individualized nutrition counseling
![Page 36: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/36.jpg)
Managing Physical Inactivity
Physical inactivity is a major risk factor for many cardiovascular diseases including coronary artery disease
Physical Activity Guideline, From Health Canada recommends a target of 30-60 minutes of moderate intensity physical activity 4-5 days of the week
Cardiac rehab offers education sessions about the heart health benefits of daily exercise and active living
Supervised exercise program and support in determining goals for independent exercise
![Page 37: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/37.jpg)
Stress,Depression,Anxiety
Established as predictors of coronary artery disease and can lead to a heart attack
Depression found to complicate recovery from cardiovascular events as well as an increase in 1 year mortality after heart attack
Increase susceptibility to other risk factors i.e. smoking, inactivity.
![Page 38: Living with cardiovascular disease](https://reader034.vdocuments.site/reader034/viewer/2022052522/554b1a61b4c90569098b4fff/html5/thumbnails/38.jpg)
Managing Stress,Depression and Anxiety
Acknowledge and discuss emotions and reactions that accompany a change in health. Many are normal and a necessary part of recovery
Learning and support may occur through shared experiences and emotions related to coping with heart disease as well as group education to assist in recognizing signs of poor coping
Individual counseling with Social Work
