CHF and Salt Retention

When CHF reduces oxygen delivery, the kidneys hold onto more salt and water, leading to swelling (edema) and fluid build-up. This is the body trying to compensate for the reduced blood flow.

Signup and view all the flashcards

What are the symptoms of CHF?

CHF symptoms include swelling in the legs and feet (peripheral edema), fluid in the lungs (pulmonary edema), difficulty breathing (SOB), tiredness (fatigue), bluish skin (cyanosis), and shortness of breath with exertion (exertional dyspnea).

What's the difference between Arteriosclerosis and Atherosclerosis?

Arteriosclerosis is the general hardening of arteries. Atherosclerosis is a specific type of arteriosclerosis caused by plaque buildup within the artery walls, further narrowing the blood flow.

What is Unstable Angina?

Unstable Angina is a serious warning sign, indicating a high risk of heart attack. It means chest pain that is more severe, frequent, and unpredictable, often occurring at rest.

Study Notes

Congestive Heart Failure (CHF)

  • Definition: A chronic condition where the heart struggles to pump blood efficiently.
  • Causes: Coronary artery disease (CAD), hypertension, and valvular heart disease.
  • Symptoms: Fatigue, shortness of breath (dyspnea), swelling in the legs/feet (edema), fluid retention causing pulmonary congestion.
  • Types: Left-sided (lung-related symptoms) and right-sided (systemic symptoms).
  • Treatment: Lifestyle changes (low-sodium diet, exercise), medications (diuretics, ACE inhibitors, beta-blockers), advanced cases may require implantable devices or heart transplants.

Myocardial Infarction (MI)

  • Definition: Commonly called a heart attack; blood flow to the heart muscle is blocked, causing damage or death.
  • Causes: Blockage in coronary arteries due to atherosclerosis or a blood clot.
  • Symptoms: Chest pain (often radiating to other areas), shortness of breath, nausea, cold sweats, atypical symptoms in women and diabetics (such as fatigue, indigestion, other possible symptoms).
  • Diagnosis: ECG changes, elevated cardiac biomarkers (e.g., troponins).
  • Treatment: Immediate interventions include aspirin, nitroglycerin, oxygen, thrombolytics, or percutaneous coronary intervention (PCI). Thereafter, long-term treatment involves statins, ACE inhibitors, beta-blockers, and lifestyle modifications.

Angina Pectoris

  • Definition: Chest pain or discomfort due to insufficient blood flow to the heart muscle.
  • Types: Stable angina (predictable, relieved with rest or nitroglycerin), unstable angina (unpredictable, medical emergency), Prinzmetal's angina (caused by coronary artery spasm).
  • Symptoms: Pressure, tightness, or burning sensation in the chest.
  • Treatment: Acute treatment with nitroglycerin; chronic treatment involves beta-blockers, calcium channel blockers, and lifestyle changes; revascularization (e.g., stenting) may be considered.

Coronary Artery Disease (CAD)

  • Definition: Narrowing or blockage of coronary arteries due to plaque buildup (atherosclerosis).
  • Risk Factors: Smoking, high cholesterol, hypertension, diabetes, obesity, sedentary lifestyle.
  • Symptoms: Often asymptomatic until blockage develops; symptoms can include angina, shortness of breath, and fatigue.
  • Complications: Heart attack (MI), heart failure, and arrhythmias.
  • Treatment: Medications (statins, antiplatelets, ACE inhibitors) to improve blood flow, reduce plaque buildup, and prevent clots.

Arrhythmias

  • Definition: Abnormal heart rhythms, too fast (tachycardia), too slow (bradycardia), or irregular.
  • Types: Atrial fibrillation (AFib), ventricular tachycardia/fibrillation, bradyarrhythmias, supraventricular tachycardia (SVT).
  • Causes: Electrolyte imbalances, CAD, heart failure, medications, and structural heart diseases.
  • Symptoms: Palpitations, dizziness, fainting, and chest discomfort.
  • Treatment: Medications (sodium channel blockers, beta-blockers), procedures like cardioversion or catheter ablation, and implantable devices.

Arteriosclerosis and Atherosclerosis

  • Arteriosclerosis: General term for thickening, hardening, and loss of elasticity in arterial walls (caused by aging, hypertension, wear and tear).
  • Atherosclerosis: A specific type of arteriosclerosis; characterized by the build-up of fatty deposits (plaque) in the arteries.
  • Causes of Atherosclerosis: High cholesterol, smoking, high blood pressure, and diabetes.
  • Impact of Atherosclerosis: Narrows arteries, restricts blood flow, increases risk of clots, angina, heart attacks, and strokes.

Angina (Chest Pain)

  • Definition: A symptom of reduced blood flow to the heart muscle (ischemia), often due to narrowed or blocked coronary arteries.
  • Types: Stable, unstable, and variant angina.
  • Impact: Temporary pain or discomfort, but does not cause permanent heart damage.
  • Important Note: Angina is the symptom, not a disease in itself.

Myocardial Infarction (MI)

  • Definition: Commonly known as a heart attack.
  • Cause: Blood flow to a part of the heart is completely blocked leading to muscle damage or death. Often the blockage is a result of an atherosclerotic plaque rupturing and forming a blood clot.
  • Symptoms: Severe, pressure-like chest pain, shortness of breath, nausea, sweating and can present atypically in women or diabetics.
  • Impact: Permanent heart muscle damage, potential for heart failure, or potentially fatal arrhythmias.
  • (Important Note): MI is a very serious event, requiring immediate professional medical attention.
