Severe mental illness: cardiovascular risk assessment and management.

Patients with severe mental illness (SMI) including schizophrenia and bipolar disorder die on average 15-20 years earlier than the general population often due to sudden death that, in most cases, is caused by cardiovascular disease. This state-of-the-art review aims to address the complex association between SMI and cardiovascular risk, explore disparities in cardiovascular care pathways, describe how to adequately predict cardiovascular outcomes, and propose targeted interventions to improve cardiovascular health in patients with SMI. These patients have an adverse cardiovascular risk factor profile due to an interplay between biological factors such as chronic inflammation, patient factors such as excessive smoking, and healthcare system factors such as stigma and discrimination. Several disparities in cardiovascular care pathways have been demonstrated in patients with SMI, resulting in a 47% lower likelihood of undergoing invasive coronary procedures and substantially lower rates of prescribed standard secondary prevention medications compared with the general population. Although early cardiovascular risk prediction is important, conventional risk prediction models do not accurately predict long-term cardiovascular outcomes as cardiovascular disease and mortality are only partly driven by traditional risk factors in this patient group. As such, SMI-specific risk prediction models and clinical tools such as the electrocardiogram and echocardiogram are necessary when assessing and managing cardiovascular risk associated with SMI. In conclusion, there is a necessity for differentiated cardiovascular care in patients with SMI. By addressing factors involved in the excess cardiovascular risk, reconsidering risk stratification approaches, and implementing multidisciplinary care models, clinicians can take steps towards improving cardiovascular health and long-term outcomes in patients with SMI.

[Calcium scoring and cardiovascular risk assessment in patients with schizophrenia].

Coronary artery disease is a major contributor to increased mortality rates in patients with schizophrenia in whom less treatment of cardiovascular (CV) risk factors is seen. Risk prediction models used in the general population are not sufficient to predict CV mortality in patients with schizophrenia. Measurement of calcium score (CACS) by cardiac CT-scan improves risk prediction in the general population, but has not been investigated in patients with schizophrenia. CACS might contribute to improved CV risk assessment and treatment in these patients and further studies should address this.

The significance of ST-elevation in aVL in anterolateral myocardial infarction: An assessment by cardiac magnetic resonance imaging.

BACKGROUND: Anterolateral myocardial infarction (MI) is traditionally defined on the electrocardiogram by ST-elevation (STE) in I, aVL, and the precordial leads. Traditional literature holds STE in lead aVL to be associated with occlusion proximal to the first diagonal branch of the left anterior descending coronary artery. However, concomitant ischemia of the inferior myocardium may theoretically lead to attenuation of STE in aVL. We compared segmental distribution of myocardial area at risk (MaR) in patients with and without STE in aVL. METHODS: We identified patients in the MITOCARE study presenting with a first acute MI and new STE in two contiguous anterior leads from V1 to V6 , with or without aVL STE. Patients underwent cardiac magnetic resonance imaging 3-5 days after acute infarction for quantitative assessment of MaR. RESULTS: A total of 32 patients met inclusion criteria; 13 patients with and 19 without STE in lead aVL. MaR > 20% at the basal anterior segment was seen in 54% of patients with aVL STE, and 11% of those without (p = 0.011). MaR > 20% at the apical inferior segment was seen in 62% and 95% of patients with and without aVL STE, respectively (p = 0.029). The total MaR was not different between groups (44% ± 10% and 39% ± 8.3% respectively, p = 0.15). CONCLUSION: Patients with anterior STEMI and concomitant STE in aVL have less MaR in the apical inferior segment and more MaR in the basal anterior segment.
