Screening for Atrial Fibrillation in Patients With Cancer: A Pilot Randomized Controlled Clinical Trial (SARIC)

March 31, 2026 updated by: University of Oklahoma
Patients with cancer have a higher incidence of AF but despite the higher incidence of AF in the cancer population, there are no randomized controlled trials (RCTs) for AF screening in this population. RCTs of AF screening in the general population have shown that screening can effectively detect AF earlier, and helps to identify candidates for appropriate anticoagulation that may lead to improvement in clinical outcomes.

Conditions

Intervention / Treatment

Detailed Description

The Investigators will conduct an open label, prospective, pilot RCT. After informed consent, patients will be randomized 1:1 into screening or usual care. Screening will be done at a single time point. Patients randomized to screening will undergo a 30-second ECG using the Kardia Mobile device (AliveCor Inc, Cupertino, CA) paired with an iPad (Apple, Cupertino, CA). Patients randomized to usual care will not receive a screening ECG. Primary outcome will be detection of newly diagnosed AF by screening vs usual care.

Eligibility Criteria

Ages Eligible for Study

65 years to 90 years (Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Male and female patients age ≥65 with a current diagnosis or history of cancer.
  2. Patients currently undergoing or history of chemotherapy, radiotherapy or cancer related surgeries will be included.
  3. The age is restricted to ≥65 years because prevalence of AF is extremely low. .

Exclusion Criteria:

  1. Known history of atrial fibrillation.
  2. Non-English-speaking participants will not be enrolled

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Screen group
Patients randomized to screening will undergo a 30-second ECG using the Kardia Mobile device (AliveCor Inc, Cupertino, CA) paired with an iPad (Apple, Cupertino, CA). If the mobile ECG shows possible AF or unclassified, then patients will undergo a 12-lead standard ECG during the same visit, read by a cardiologist, to verify the correct diagnosis.
Diagnostic test: 30-second ECG using the Kardia Mobile
30-second ECG using the Kardia Mobile
Active Comparator: Usual Care
For patients in the usual care arm, medical record review will be done at end of study to assess for the newly diagnosed AF during the study period.
Other: routine care
medical review

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The Investigators will compare the incidence of newly diagnosed AF identified by screening versus usual care
Time Frame: 6 MONTHS
To compare the incidence of newly diagnosed AF with point-of-care screening using a mobile, single-lead ECG versus usual care, in patients with a diagnosis of solid cancer. In this open-label, prospective pilot RCT, patients (n=480) with AF and solid cancer presenting for an outpatient visit will be randomized 1:1 to screening versus usual care. A 30-second screening ECG will be done using the Kardia Mobile device (AliveCor Inc, Cupertino, CA) paired with an iPad. The Investigators will compare the incidence of newly diagnosed AF identified by screening versus usual care.
6 MONTHS

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To determine the effect of screening-detected AF on initiation of anticoagulation.
Time Frame: 6 MONTHS
To determine the effect of screening-detected AF on initiation of anticoagulation. Patients diagnosed with AF through screening will be referred to their primary care physician for initiation of anticoagulation based on their CHA2DS2VASc score.The Investigators will conduct chart review at the end of study to compare the proportion of patients appropriately initiated on anticoagulation between screening versus usual care.
