Insights

Cardiac resynchronisation therapy (CRT) improves outcomes for heart failure patients. This study found high implantation success and low mortality, but noted a persistent high rate of heart failure hospitalizations in daily practice.

Area of Science:

  • Cardiology
  • Medical Devices
  • Heart Failure Management

Background:

  • Cardiac resynchronisation therapy (CRT) is established for heart failure, but real-world clinical consequences require further evaluation.
  • Optimal pharmacological therapy preceded CRT implantation in eligible patients.
  • This study assesses CRT outcomes in a single center's patient cohort.

Purpose of the Study:

  • To evaluate the clinical outcomes of cardiac resynchronisation therapy (CRT) in a real-world clinical setting.
  • To analyze implantation procedures, hospitalizations, mortality, and device-related events in CRT patients.
  • To compare single-center CRT outcomes with published data.

Main Methods:

  • Retrospective analysis of 119 consecutive patients undergoing CRT implantation between November 2000 and January 2006.
  • Data collection included implantation success rates, procedural complications, hospital admissions (cardiac and non-cardiac causes), mortality causes, and device-related events.
  • Five-year cumulative survival was estimated.

Main Results:

  • CRT implantation was successful in 97% of patients, with a low prevalence of procedural complications (8 patients).
  • During follow-up, 22 patients (18.5%) died from various causes, including heart failure (11) and sudden cardiac death (4).
  • The estimated five-year cumulative survival was 70%, with 81 hospitalizations, predominantly for cardiac reasons (77).

Conclusions:

  • The study demonstrated a high procedural success rate and low mortality for CRT, aligning favorably with other research.
  • Despite improvements in functional capacity, a significant rate of heart failure-related hospitalizations persisted in daily practice.
  • Single-center data suggests CRT is safe and effective, but ongoing management of heart failure remains crucial.

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

Dysrhythmias VII: Nursing Management of Dysrhythmias

Nursing management of dysrhythmias involves the following:AssessmentSubjective Assessment:The initial step involves gathering patient-reported symptoms such as dizziness, palpitations, and chest discomfort. It is crucial to collect a detailed history, including previous heart conditions, current medication use, and lifestyle factors like caffeine and alcohol consumption.Objective Assessment:This involves observing clinical signs such as jugular venous distention, cool and pale skin, and...
Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
