Cardiovascular disease (CVD) specialists have faced many challenges during the COVID-19 pandemic starting with a critical role in caring for severely ill patients with COVID-19, recognising the cardiovascular complications of COVID-19, performing and publishing clinical studies on cardiac involvement, and unravelling whether the shared pathophysiological mechanisms of COVID-19 infection and some cardiovascular medications might affect disease severity. Simultaneously, cardiovascular specialists have continued to provide care to patients with acute and chronic CVD in the context of infection control measures and limited resources during a pandemic. In addition, as healthcare providers, we are public role models for responsible personal behaviour during a pandemic including social distancing, hand washing and wearing a face mask. The graphic by Rajagopalan and colleagues1 that shows how far droplets and aerosols spread with a cough or sneeze might help convince more people that widespread use of masks is needed, at least until we have an effective vaccine for this virus (figure 1).
In this issue of Heart, we present a review articles by Rowland and Kunadian2 discussing management of older patients with acute coronary syndromes and one by Radke and colleagues3 addressing care of adults with congenital heart disease during the COVID-19 pandemic (figure 2). These articles provide a useful starting point for thinking about how to structure clinical care for these patient groups although, of course, the response at your own institution will depend on local resources and disease activity. The pandemic has accelerated alternate approaches to patient care, such as telemedicine patient visits, and gives us pause to reconsider the frequency and number of diagnostic tests we use in management of these patients. Could we provide effective medical care more efficiently even after the pandemic is over? It also has highlighted the need to protect both our patients and ourselves from transmitting the virus while ensuring continuity of care. At the same time, we need medical care to be accessible for patients with acute cardiovascular conditions, a challenge affected by societal factors as much as by the healthcare system itself.
The importance of secondary CVD prevention in adults after a cardiac event is well established yet many patients fail to take appropriate medications. In order to identify individual characteristics associated with use of secondary CVD preventative medications, Lu and colleagues4 studied the 74 830 participants with known CVD in the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project, out of a total participant group of over 2.6 million people aged 35–75 years of age. The overall use of secondary prevention medications was quite low; 31 .% used antiplatelet drugs, 11% used statins and 8.3% used both medications. Those less likely to use secondary prevention medications were younger, women, current smokers, current drinkers, those without hypertension or diabetes and those with known CVD for longer than 2 years (figure 3). Although this data is specific to China, it is thought-provoking that we might be able to improved CVD outcomes by identifying and targeting patient groups who would benefit from secondary prevention therapies but are likely to be undertreated.
An additional preventable risk factor for CVD that often is not considered is childhood maltreatment (abuse and neglect). Soares and colleagues5 provide data from the UK Biobank showing a consistent association between childhood maltreatment and CVD with stronger associations observed in women compared with men. In an editorial, Li and Lacey6 discuss potential mechanisms of this association and conclude: ‘If the association indeed differs by gender, it will be crucial to further explore the mechanisms and life course pathways that may contribute to the gender-specific associations and also the timing of their emergence, which may indicate a sensitive period during which intervention could lead to improvements in adult cardio-metabolic health, especially for women.’
Another article of particular interest in this issue of Heart is the identification of a novel autosomal-recessive gene, TRIM63, causing hypertrophic cardiomyopathy (HCM) with a high rate of left ventricular dysfunction.7 As Kuusisto points out in an editorial,8 although this is one more of many genes associated with HCM: ‘Discovering the genetic basis of HCM has given us valuable information about the inheritance, pathogenesis and heterogeneity of the disease. In the future, genetic diagnosis will be even more important as targeted gene-specific therapies emerge.’
The Education in Heart article in this issue discusses diabetes mellitus (DM) and heart disease9 emphasising that all patients with DM are at higher risk of CVD; with risk classified as moderate (age <50 years with DM duration <10 years), high (DM >10 years without target organ damage or other risk factors) and very high (DM and established CVD, target organ damage, at least three risk factor or DM >20 years). Two new classes of glucose-lowering medications—sodium glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists reduce the risk of CVD10 and current guidelines recommend these agents as first line therapy in patients at high or very high risk (figure 4).
