Heart Disease• Cardiovascular disease – an abnormal
condition that affects the heart and blood vessels.
• Coronary heart disease – occurs when the arteries that supply blood to the heart muscle harden and narrow.

Common Causes of Heart Disease• Age• Gender• Heredity • Stress• Diabetes• Smoking • Alcohol Consumption• High blood pressure • High blood cholesterol • Being overweight or obese • Physical inactivity

Controlling Risk Factors
• Changing One’s Lifestyle– Stop smoking/ Do not start smoking– Change diet• Avoid saturated fats and cholesterol
– Exercise regularly

Heart Attack• Myocardial Infarction - Death
of or damage to part of the heart muscle due to an insufficient blood supply.
• The term "heart attack" refers to death of heart muscle tissue due to the loss of blood supply, not necessarily resulting in a cardiac arrest or the death of the heart attack victim.

Signs & Symptoms of a Heart Attack• Chest Pain– Chest, shoulder, arm, jaw– Last longer than 3 – 5 minutes or goes
away and comes back
• Difficulty breathing– Short of breath– Breathes faster than normal
• Skin Appearance– Skin may be moist or sweating profusely – Skin may appear pale or ashen
• Men vs. Women

When to call 9-1-1
• Victims often deny signals are serious• Do not let this influence your decision to call
9-1-1 • Most people who die of a heart attach die
within 2 hours of the first signal

Giving Aspirin to Lessen Heart Attack Damage -
• If the person is able to take medicine by mouth ask – – Are you allergic to aspirin– Do you have a stomach ulcer or stomach disease?– Are you taking any blood thinners, such as
warfarin?– Have you ever been told by a doctor to avoid
taking aspirin?
![Page 9: Chapter 5 Cardiac Emergencies. Heart Disease Cardiovascular disease – an abnormal condition that affects the heart and blood vessels. Coronary heart disease](https://reader036.vdocuments.us/reader036/viewer/2022062423/5697bff61a28abf838cbe3e0/html5/thumbnails/9.jpg)
Giving Aspirin to Lessen Heart Attack Damage -
• If the person answers NO to all of these questions, you may offer him or her two chewable (81 mg) baby aspirins or one 5 grain (325 mg)adult aspirin with a small amount of water.
• You may offer these doses of aspirin if the person regains consciousness while you are giving care and is able to take the apirin by mouth.

Cardiac Arrest
• Cardiac arrest is the sudden, abrupt loss of heart function.
• Most cardiac arrests occur when the electrical impulses in the diseased heart become rapid (ventricular tachycardia) or chaotic (ventricular fibrillation) or both.
• This irregular heart rhythm (arrhythmia) causes the heart to suddenly stop beating.
• The term "massive heart attack" is often wrongly used in the media to describe sudden death from cardiac arrest.

Cardiac Chain of SurvivalFor each minute CPR and defibrillation are delayed,
the chance of survival is reduced by about 10 percent.
• Early recognition and early access
• Early CPR
• Early defibrillation• Early advanced medical
care

Cardiopulmonary Resuscitation
• CPR is a method that combines chest compressions and rescue breathing for a victim who is not breathing and has no pulse.
• This technique provides oxygenated blood to vital organs until advanced care arrives.
• Given together, rescue breaths and compressions help to take over for the heart and lungs.

If Two Responders Are Available
• If the 1st responder is tired and needs help, they should tell the second responder to take over.
• The 2nd responder should immediately resume CPR, starting with chest compressions.
![Page 16: Chapter 5 Cardiac Emergencies. Heart Disease Cardiovascular disease – an abnormal condition that affects the heart and blood vessels. Coronary heart disease](https://reader036.vdocuments.us/reader036/viewer/2022062423/5697bff61a28abf838cbe3e0/html5/thumbnails/16.jpg)
When to stop CPR -
• The person shows signs of life• An AED becomes available and is ready to use• Another trained responder arrives and takes over• You are too exhausted to continue• The scene becomes unsafe
![Page 17: Chapter 5 Cardiac Emergencies. Heart Disease Cardiovascular disease – an abnormal condition that affects the heart and blood vessels. Coronary heart disease](https://reader036.vdocuments.us/reader036/viewer/2022062423/5697bff61a28abf838cbe3e0/html5/thumbnails/17.jpg)
Continuous Chest Compressions(Hands Only CPR)
• If you are unable or unwilling to perform full CPR give continuous chest compressions after calling 9-1-1.

Advance DirectivesInstructions that describe a person’s wishes about medical treatment.
• Adults who are admitted to a health care facility have the right to make fundamental choices about their own care.
• Two examples of written directives are – Living Wills– Durable Powers of Attorney
• Do Not Resuscitate or Do Not Attempt Resuscitation (DNR/DNAR)
