Recognizing essential actions in emergencies, like starting compressions for unresponsive patients, is critical for effective response.

Cardiovascular Disorders Overview

Decline in overall cardiovascular deaths highlights improvements in care.
Nurses play a critical role in awareness, interventions, and patient education for cardiovascular disorders.

Effects of Normal Aging

Physiological changes reduce heart efficiency with age.
Older adults with high cholesterol should stop smoking, increase activity, manage weight, and control blood glucose.

Risk Factors for Cardiovascular Disease

Risk factors classified as non-modifiable (age, genetics, gender) and modifiable (smoking, hyperlipidemia, hypertension, diabetes, obesity, sedentary lifestyle, stress, type D personality).
Presence of multiple risk factors significantly increases cardiovascular disease risk.

Modifiable Risk Factors

Smoking: Leads to tachycardia, hypertension, vasoconstriction; interventions include cessation and lifestyle changes.
Hyperlipidemia: Managed by controlling diet, weight, exercise, and cholesterol levels.
Diabetes: Damages vessels, alters metabolism; requires management of blood glucose and blood pressure.
Obesity: Increases heart workload and cardiovascular event risk; intervention includes decreasing BMI.
Sedentary Lifestyle: Regular aerobic exercise improves efficiency and lowers blood glucose; contributes to better lipid ratios.
Stress and Type D Personality: Chronic stress releases catecholamines affecting heart health; managing stress can mitigate risks.

Acute Coronary Syndrome (ACS)

Encompasses stable angina, unstable angina, and acute myocardial infarction (MI).
Pathophysiology involves reduced blood flow and oxygen demand, usually due to atherosclerosis.
MI types include Type I (plaque rupture) and Type II (imbalance in oxygen supply and demand).

ACS Assessment and Diagnosis

Classic symptoms can differ in men and women; silent infarctions may occur.
Diagnosis involves symptom assessment, ECG, cardiac enzyme tests, and possibly cardiac catheterization.

ACS Medical Management

Goals: reperfusion, reducing infarct size, preventing complications, pain relief, emotional support, and patient education.
Interventions include thrombolytics, oxygen, and other medications to restore blood flow.

Nursing Considerations

Monitor hemodynamics, watch for complications such as bleeding, dysrhythmias, and re-occlusion.
Desired patient outcomes include adequate cardiac output, pain relief, and positive coping.

Code Management and Resuscitation

Basic Life Support (BLS) focuses on restoring circulation, oxygenation, and ventilation.
Advanced Cardiac Life Support (ACLS) includes airway management, ventilation, and reversible cause identification (H's and T's).

Recognition and Treatment of Dysrhythmias

Identifies shockable (ventricular fibrillation, pulseless ventricular tachycardia) and non-shockable rhythms (pulseless electrical activity, asystole).
Symptomatic bradycardia requires careful monitoring and potential treatment.

Goals of Post-Resuscitation

Focus on optimizing cardiopulmonary function, tissue perfusion, and identifying the cause of cardiac arrest.
Monitor for dysrhythmias and metabolic concerns while providing emotional support.

A/V Junctional Rhythm and Conduction Blocks

Junctional rhythm originates from a conduction block proximal to the AV node, often due to ischemia or myocardial infarctions.
Ventricular pacing occurs independently from an ectopic focus, typically at a rate of 40-60 bpm, characterized by absent P-waves and prolonged QRS complexes.

Cardiac Function and Blood Flow

Blood is pumped from the right atrium to the right ventricle, then through the pulmonary artery to the lungs for oxygenation.
Afterload refers to the resistance ventricles must overcome to eject stroke volume into the systemic circulation.

Cardiac Emergency Response

Primary nurse actions during a code include starting IV lines, measuring vital signs, and administering emergency medications.
Adequate electrode skin preparation involves hair clipping, skin cleansing, and ensuring dry sites for proper adherence.

Heart Sounds and Coronary Circulation

Heart sounds are produced by valve closures: S1 ("lub") marks AV valve closure and S2 ("dub") marks semilunar valve closure.

Blood enters the right atrium after passing through the vena cavae.

Right Heart Function

Blood travels from the right atrium to the right ventricle through the tricuspid valve.
The right ventricle pumps blood out via the pulmonic semilunar valve into the pulmonary arteries.
Blood is transported to the lungs for oxygenation and returns to the heart through the pulmonary veins.

Left Heart Function

Oxygen-rich blood enters the left atrium from the pulmonary veins.
Blood flows from the left atrium down to the left ventricle through the mitral valve.
The left ventricle pumps blood into the body through the aortic semilunar valve and into the aorta.

Coronary Circulation

Coronary arteries supply blood to the myocardium (heart muscle), ensuring it receives necessary oxygen and nutrients.

Key Concepts

Veins carry blood toward the heart; arteries carry blood away from the heart.

Risk Factors for Cardiovascular Disease

Modifiable risk factors include hyperlipidemia and active lifestyle.
Non-modifiable factors: age and family history.

Types of Arrhythmias

Ventricular fibrillation is the most serious type of arrhythmia.

Nursing Care for Pacemaker Patients

Monitor heart rate and rhythm using apical pulse and ECG, no MRI scheduling needed, and bed rest isn't always required.
Avoid range-of-motion exercises on pacemaker side for the first 2 days.

Treatment for Myocardial Infarction

Thrombolytic agents are essential within 24 hours to minimize infarct size; morphine is contraindicated for CNS side effects.
Patients are typically on bed rest with limited privileges for 24 to 48 hours.

Angina Pectoris

Indicates insufficient oxygen and blood supply to the heart.
Symptoms may resemble heartburn; pain may present as jaw discomfort.
Usually relieved by nitroglycerin, and does not only occur at rest.

Blood Circulation Pattern

Blood circulation sequence:
- Superior/inferior vena cava → Right atrium → Tricuspid valve → Right ventricle → Pulmonary semilunar valve → Pulmonary artery → Lung capillaries → Pulmonary veins → Left atrium → Bicuspid valve → Left ventricle → Aortic semilunar valve → Aorta.
