El cuidado de pacientes con mayor riesgo de fallo prematuro del marcapasos
JAMA
|February 16, 1979
Resumen
Los recordatorios de marcapasos debido a la falla prematura requieren un manejo cuidadoso del paciente. Estrategias como el reemplazo proactivo o el monitoreo mejorado reducen significativamente los riesgos asociados con el mal funcionamiento del dispositivo.
Área de la Ciencia:
- Cardiología Cardiología.
- Ingeniería Biomédica Ingeniería Biomédica.
- Seguridad de los Dispositivos Médicos.
Sus antecedentes:
- Un fabricante de marcapasos emitió retiros para dispositivos con mayor riesgo de fallo repentino y prematuro.
- Este estudio analizó las respuestas de los pacientes a estos retiros que involucraron a 217 personas.
Objetivo del estudio:
- Evaluar los resultados de las diferentes estrategias de gestión después de los avisos de retiro de marcapasos.
- Evaluar el impacto de las respuestas de retiro en la seguridad y la mortalidad de los pacientes.
Principales métodos:
- Los pacientes se clasificaron en tres grupos: cambio profiláctico del generador de pulsos, vigilancia aumentada y vigilancia de rutina.
- Monitoreó las fallas del dispositivo y los resultados de los pacientes durante un período de tres años después de la implantación.
Principales resultados:
- Se observaron 30 fallas repentinas y 19 incidentes de disminución de la velocidad que indican un fallo inminente, todos manejados con éxito mediante la sustitución.
- La mortalidad general fue comparable a otras series de marcapasos, con seis muertes que tenían datos inadecuados sobre el estado del marcapasos.
Conclusiones:
- Las decisiones de gestión para los retiros de marcapasos deben considerar la frecuencia de falla, el modo de falla, la dependencia del ritmo del paciente y las comorbilidades.
- Las estrategias proactivas y la vigilancia vigilante son cruciales para mitigar los riesgos asociados con los marcapasos retirados del mercado.

Imbalances in Cardiac Output
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...

Heart Failure V: Medical Management
Medical Management of Acute Decompensated Heart Failure (ADHF)The primary goals of therapy for patients hospitalized with acute decompensated heart failure (ADHF) include:Relieving symptomsOptimizing volume statusSupporting oxygenation and ventilationMaintaining cardiac output (CO) and end-organ perfusionIdentifying and addressing the cause of ADHFPreventing complicationsProviding patient education on factors precipitating HF exacerbationPlanning for dischargeOngoing monitoring and assessment...
Heart Failure VI: Adjunct Therapies
Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.
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,...
Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
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...
