Angina V: Nursing Management01:20

Angina V: Nursing Management

Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...

Antianginal Drugs: Nitrates and β-Blockers

In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates,  such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...

Angina IV: Management

IntroductionThe management of angina requires a comprehensive approach that includes pharmacological therapies, medical procedures, and lifestyle modifications.Pharmacological TherapiesAntiplatelet agents, such as aspirin, clopidogrel, prasugrel, and ticagrelor, play a pivotal role in preventing thrombus formation in patients with angina. These medications inhibit platelet aggregation and reduce the likelihood of myocardial infarction and other cardiovascular events.Anticoagulants, including...

Acute Coronary Syndrome V: Nursing Management

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.
Drugs in...
Aortic Regurgitation IV: Nursing Management01:17

Aortic Regurgitation IV: Nursing Management

A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...

Summary

Sublingual nitroglycerin (SLN) is a key treatment for angina, but many patients lack knowledge about its proper use. Healthcare providers may also overlook prescribing SLN, impacting effective angina self-management.

Area of Science:

  • Cardiology
  • Pharmacology
  • Patient Education

Background:

  • Sublingual nitroglycerin (SLN) is a primary treatment for stable angina.
  • Anecdotal evidence suggests healthcare professionals may overlook SLN in angina self-management.
  • This highlights a potential gap in patient care and education.

Purpose of the Study:

  • To assess patient knowledge and utilization of SLN.
  • To identify barriers to consistent SLN prescription and use.
  • To inform strategies for optimizing SLN therapy in angina self-management.

Main Methods:

  • A questionnaire was administered to 300 patients.
  • The survey explored patient knowledge and use of SLN.
  • Data collection focused on prescription patterns and administration understanding.

Main Results:

  • Patients with coronary artery disease are not consistently prescribed SLN.
  • Significant knowledge deficits exist regarding SLN dosage and administration.
  • Many patients were unaware of SLN prophylaxis and concurrent topical nitrate use.

Conclusions:

  • There are critical gaps in patient knowledge and healthcare provider prescribing of SLN.
  • Optimizing SLN therapy requires improved patient education and consistent clinical practice.
  • Addressing these issues is crucial for effective angina self-management.
