Short-term Effect of Stock volatility and Cardiovascular Mortality: A systematic review and meta-analysis

INTRODUCTION: Cardiovascular diseases (CVD) and stroke are leading causes of death. It has several risk factors including stress and pressure. Stock volatility can cause acute stress for stock holders, so it can cause CVD events. Recently the spread of new coronaviruses worldwide has greatly affected economic development, leading to more severe stock market fluctuation, so we systematically quantify the short-term effect of stock volatility and CVD events.METHODS AND MATERIALS: Time-series analysis on effect of stock volatility and cardiovascular events were included. We conducted systematic review and meta-analysis. 4 studies were included in the final analysis.RESULTS: Every 100-point increase in the stock market will bring about 1.01% increases in the cardiovascular mortality (95% CI, -0.18% to 2.21%) The meta-analysis showed no statistical significance for cardiovascular mortality. In terms of stroke event, the estimate effect was 2.999% (95%CI, 0.325% to 5.673%). Different lag patterns also had effects on cardiovascular mortality. Every 100-point increase brought about 4.026% (95%CI, 1.516% to 6.536%) and 4.424% (95%CI, 1.145% to 7.703%) for lag 01 and 04 separately. Conclusions: Our study suggested that stock volatility had lag effect on CVD mortality. It may last for several days. Also, it might increase the incidence of stroke.
