Ischemic Heart Diseases: *Angina pectoris - Care Plan - | Stress reduction protocol. Med consult recommended. Cardiac dose of up to 0.04 mg of vasoconstrictor should be used (no more than two cartridges of 1:100,00 epinephrine or four cartridges of 1:200,000) with stable angina. Postpone tx for unstable angin |
Ischemic Heart Diseases: *Angina pectoris - Follow up Q's - | What usually causes your angina episode? How often does angina occur? How long does it last? Do you use nitroglycerin to manage the pain? Have you ever needed to call for emergency assistance because of angina? Have you ever had a heart attack? |
Ischemic Heart Diseases: * Myocardial Infarction * | Occurs when the blood supply to the heart is blocked causing death and/or damage to the heart muscle. |
Ischemic Heart Diseases: *Myocardial Infarction - Thrombosis - | Primary cause of a MI. Blood clot attached to the intima of a blood vessel, occludes the lumen. |
Ischemic Heart Diseases: *Myocardial Infarction - Embolism - | Secondary cause of a MI. Sudden blockage of an artery by a blood clot or foreign material, unattached, traveling through the blood stream. |
Ischemic Heart Diseases: *Myocardial Infarction - Symptoms | •Same symptoms as angina: squeezing sensation or pain in the chest that may radiate to the arms, neck, back, or jaw, Levine sign, difficulty in breathing/dizziness, diaphoresis. Not relieved by nitroglycerin. |
Ischemic Heart Diseases: *Myocardial Infarction - Emergency Treatment | Position comfortably. Administer 100% oxygen Monitor vitals (BP usually falls during an MI) Administer nitroglycerine tablets One tablet every 5 minutes up to 3 doses (if systolic BP > 90) Administer 162 to 325 mg of chewable aspirin. |
Ischemic Heart Diseases: *Myocardial Infarction - If Nitro isn't working - | If not responding after 2nd tablet nitroglycerine activate EMS. If no pain relief from nitro, administer 30% Nitrous Oxide If cardiac arrest occurs: CPR or defibrillator while waiting for EMS to arrive. |
Ischemic Heart Diseases: *Myocardial Infarction - Care Plan | Postpone elective dental treatment for 6 months. Check INR if on blood thinner,(INR should be within therapeutic range of 2.0-3.0). Nitrous OK. Limit epinephrine to cardiac dose IF vasoconstrictor is necessary but should consult with physician. |
Ischemic Heart Diseases: *Myocardial Infarction - Follow up Q's | When was your heart attack? Any complications? When was your last visit with your physician? Medications: what, how much, and when (regularly and today)? |
Ischemic Heart Diseases: * Congestive Heart Failure * | Imbalance between the demand placed on the heart and its ability to respond. Involves failure of one or both ventricles. Results in an inadequate supply of blood and oxygen throughout the body and congestion of blood within the vascular system. |
Ischemic Heart Diseases: *Congestive Heart Failure - Underlying Causes - | Myocardial Infarction Hypertension Congenital heart disease Heart valve damage Cardiomyopathy |
Ischemic Heart Diseases: *Congestive Heart Failure - Left Heart Failure - Symptoms | Pulmonary edema Dyspnea, SOB (relieved when sitting up) Dry cough (due to congestion in lungs) Weakness, fatigue Diastolic BP increased Rapid heart rate Pallor, sweating, cold skin Fear and anxiety |

Ischemic Heart Diseases: *Congestive Heart Failure - Emergency Care | Position pt. upright Call EMS Administer oxygen Monitor vital signs Reassure patient |
Ischemic Heart Diseases: *Congestive Heart Failure - Care Plan | Treat patient in a semi-supine position or upright Cardiac dose of epinephrine If taking Digitalis Sensitive gag reflex Avoid epinephrine Med consult based on patient’s cardiovascular history and severity of disease. No treatment unless minimal edem |
Ischemic Heart Diseases: *Congestive Heart Failure - Follow up Q's | Do you need several pillows to sleep? Do you awaken from sleep short of breath? Can you tolerate being placed in a supine chair position for treatment? Can you walk up a flight of stairs without stopping to rest? How often do you see your physician? |
***Arrhythmias*** | Any variation in the normal heartbeat includes disturbances of rhythm, rate and conduction patterns of the heart |
Arrhythmias: * Tachycardia | Abnormally rapid heart rate. >100 beat/minute |
Arrhythmias: * Bradycardia | Slowness of heartbeat. <60 beat/minute |
Arrhythmias: - Common types | Atrial fibrillation non- detrimental. Most common cause of sudden death in MI is from ventricular fibrillation. |
Arrhythmias: - Care Plan | Nitrous oxide ok. Epi may precipitate an arrhythmia or tachycardia. Cardiac dose of epinephrine ok. Epinephrine should be avoided in patients taking Digoxin. Patients on Warfarin (Coumadin) should have INR within range of 2.0-3.0 |
Arrhythmias: - Follow up Q's | When were you diagnosed? What type of arrhythmia do you have? Is your arrhythmia asymptomatic or symptomatic? Are you or have you been treated for your arrhythmia? If so, what treatment did you receive? What medications are you taking? |
Arrhythmias: * Cardiac Pacemaker * | An electronic stimulator or defibrillator used to send a specified electrical current to the myocardium to control or maintain a regular heart rate |
Arrhythmias: *Cardiac Pacemaker - Treatment Modification | If unavailable get Med Consult to determine evaluation of the device No antibiotic pre-med needed Usually no restrictions on use of ultrasonic devices |
Arrhythmias: *Cardiac Pacemaker - Follow up Q's | When was your pacemaker implanted? Does the pacemaker have a shield? When was the function last checked? Has your physician warned you about dental equipment that may interfere with your pacemaker? |
