Current status of nuclear cardiology practice in Latin America and the Caribbean, in the era of multimodality cardiac imaging approach: 2022 update

Cardiovascular testing recovery in Latin America one year into the COVID-19 pandemic: An analysis of data from an international longitudinal survey

Background

The COVID-19 pandemic disproportionately impacted Latin America (LATAM), significantly disrupting cardiovascular testing. This study evaluated cardiac procedure recovery in LATAM one year after the outbreak.

Methods

The International Atomic Energy Agency (IAEA) surveyed 669 centers in 107 countries worldwide, including 135 facilities in 19 LATAM countries, to assess cardiovascular procedure volumes in March 2019, April 2020, and April 2021, and changes in center practices and staffing conditions one year into the COVID-19 pandemic.

Findings

LATAM centers reported a 21 % decrease in procedure volumes in April 2021 from pre-pandemic-baseline, vs. a 0 % change in the rest of the world (RoW), and greater volume reductions for almost all procedure types. Centers in Central America and Mexico reported the largest procedure reductions (47 % reduction) compared to the Caribbean (15 %), and South America (14 %, p = 0.01), and this LATAM region was a significant predictor of lower procedure recovery in multivariable regression. More LATAM centers reported reduced salaries and increased layoffs of clinical staff compared to RoW, and LATAM respondents estimated that half of physician and non-physician staff experienced excess psychological stress related to the pandemic, compared to 25 % and 30 % in RoW (p < 0.001).

Conclusions

Cardiovascular testing recovery in LATAM trailed behind RoW for most procedure types, with centers in Central America and Mexico reporting the greatest volume reductions. This study found lasting impacts of COVID-19 on cardiovascular care in LATAM and the need for mental health support for LATAM healthcare workers in current and future pandemics.

How international organizations can support the development of cardio-oncology in the Latin American and the Caribbean region

Health problems in the Latin American and the Caribbean (LAC) region are highly concentrated on non-communicable diseases, being cardiovascular diseases (CVDs) and cancer the leading causes of death. Different countries of the region are at different stages of development in addressing CVDs and cancer. Opportunities for training and continuing education in cardio-oncology, as well as active cardio-oncology groups, are primarily limited to large academic institutions in major metropolitan areas. In addition, the development of advanced imaging modalities in LAC faces challenges such as the high cost of equipment, a lack of equipment maintenance and service, as well as insufficient specific training for both imaging specialists and referring clinicians. To contribute to the implementation of actionable strategies ensuring equitable access to care for all, international organizations, such as the International Atomic Energy Agency (IAEA), offer support for the regional development of health projects that address educational needs. In this context, a new IAEA regional cooperation project for LAC titled 'Strengthening of regional capacities on the use of Nuclear Medicine techniques in a Cardio-oncology multimodality approach in patients with cancer' will be developed during 2024-2025. The experience of some centres, as well as national experiences in certain countries of the region, that have been previously involved in other regional projects, can be leveraged for the benefit of the entire region. We present a proposed road map for cross-institutional/countries collaboration in the development of cardio-oncology in the LAC region, contributing to decreasing the barriers to the growth of the subspecialty.
