마을 진료소에서 고령 환자의 심방세동 및 심부전에 대한 원격의료 기반 통합 관리
마을 진료소 노인 환자의 심방세동 및 심부전에 대한 원격의료 기반 통합 치료: MIRACLE-AF II 클러스터 무작위 임상시험
연구 개요
상세 설명
심방세동(AF)과 심부전(HF)은 종종 공존하며 서로를 강화시키며, 특히 노인에게 파괴적인 '악순환'을 형성합니다. AF를 가진 노인 환자는 HF 진행에 대한 높은 위험을 가지며, AF-HF 동반 질환은 장기 예후의 중심 결정 요인입니다. 중국 농촌 지역에서는 효과적인 예방과 장기 관리가 실질적인 병목 현상에 직면해 있으며, 이에는 불충분한 조기 HF 선별 검사와 표적 예방의 부족한 강도가 포함됩니다. 이전 연구들은 표준 ABC 경로와 같은 '과정 지향적' 통합만으로는 HF 위험이 지배적인 농촌 AF 환자에게 불충분할 수 있음을 시사합니다.
이러한 격차를 해결하기 위해, MIRACLE-AF II 연구는 원격 의료와 지능형 의사 결정 지원을 바탕으로 가이드라인 지향 약물 치료(GDMT)와 다차원 생활습관 개입을 통합한 마을 의사 주도 모델을 확립하는 것을 목표로 합니다. 조기 HF 선별 검사, 약물 접근성, 확장 가능한 생활습관 개입(동료 그룹 심장 재활, 행동 교육, 스마트 웨어러블 기기 모니터링 포함)을 원격 지원 워크플로우에 통합함으로써, 이 프로젝트는 노인 환자의 임상 결과를 효과적으로 개선하려 합니다.
이는 중국 장쑤성 농촌 지역에서 수행되는 군집 무작위 대조 시험입니다. 마을 진료소는 디지털 지능 통합 관리 그룹(중재) 또는 기존 관리 그룹(대조)에 1:1 비율로 무작위 배정됩니다. 연구는 확인된 AF와 문서화된 병력 또는 선별 검사 기반 HF 진단을 가진 65세에서 80세 사이의 상주 주민을 등록합니다. 시험은 두 단계로 나뉩니다: 두 그룹 간 HF 예후 점수(MAGGIC 점수)를 비교하는 12개월 추적 관찰, 그리고 심혈관 사망, 허혈성 또는 출혈성 뇌졸중, 악화된 HF 또는 급성 관상동맥 증후군(ACS)으로 인한 입원, AF로 인한 응급 방문을 포함한 복합 종점 사건을 비교하는 36개월 추적 관찰입니다.

The proportion of patients who met all the three criteria for the ABC pathway of integrated AF care
기간: 12 month after baseline

The 'A' criterion referred to stroke prevention or anticoagulation.
'A criterion compliant' implies that either appropriate non-vitamin K antagonist oral anticoagulant (NOACs) use, or warfarin was used with a time in the therapeutic range (TTR) >65%.
Patients who were not properly treated with OACs are considered as 'A non-compliant'.
The 'B' criterion referred to better symptom control with patient-centered decisions on rate or rhythm control.
Patients with an EHRA score of I or II are considered to have good control of AF symptoms ('B compliant').
On the contrary, those with an EHRA score of III or IV were defined as 'B non-compliant', which means their symptoms were insufficiently controlled.
The 'C' criterion stands for optimal management of cardiovascular risk factors and other comorbidities.
'C criterion compliant' implies that all the considered risk factors and comorbidities were well controlled or optimally treated.
Otherwise, patients were considered as 'C non-compliant'

The proportion of patients who are eligible for guideline-directed medical therapy (GDMT) and actually receive GDMT within 12 Months.
Single-class prescription rate: Prescription rate for a given GDMT drug class = (number of patients prescribed that drug class) / (number of patients eligible for that drug class) × 100%.
At least one GDMT class prescription rate: At least one GDMT prescription rate = (number of patients prescribed at least one GDMT drug class) / (total number of patients eligible for GDMT) × 100%.

Change in MAGGIC Heart Failure Risk Score
기간: Baseline to 36 months

Description: A heart failure prognostic model integrating 13 key predictors, including age, LVEF, systolic blood pressure, BMI, serum creatinine, NYHA functional class, and medication status.
|
Baseline to 36 months

GDMT Score
기간: Baseline to 12 months
|
β-blockers are scored as 0, 1, or 2 points for no use, use at <50% of the target dose, or use at ≥50% of the target dose, respectively.
For renin-angiotensin system inhibitors, no use is scored as 0 points; ACEI/ARB therapy at <50% or ≥50% of the target dose is scored as 1 or 2 points, respectively; and ARNI therapy at any dose is scored as 3 points.
Mineralocorticoid receptor antagonists and SGLT2 inhibitors are each scored as 0 points when not used and 2 points when used at any dose.
Ivabradine and vericiguat are each scored as 0 points when not used and 1 point when used at any dose.
The scores for all medication classes are summed to obtain the total GDMT score, with a higher score indicating a greater degree of GDMT implementation.
Target doses are determined according to the relevant heart failure guidelines.
