Short answer
Not a single studyNo clear answer.
The article covers a research area rather than reporting a specific new paper, so there is no single study to check it against.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 6Not checkedExposure to light at night is linked to important and potentially harmful changes in the structure and function of the heart, according to a study of more than 11,000 people published in the European Heart Journal.View evidenceHide evidence
As statedmore than 11,000 people
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 2 of 6Not checkedThe research was led by Professor Lu Qi from Tulane University in New Orleans, and he said previous observational studies had linked nighttime light exposure with a higher risk of cardiovascular disease, but little was known about related cardiac structural and functional changes.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 3 of 6Not checkedThe study included 11,071 UK Biobank participants who wore wrist light sensors for seven days, then had cardiac MRI scans three years later; researchers compared those exposed to more than three lux at night with those exposed to almost no light at night.View evidenceHide evidence
As stated11,071 people; more than three lux; three years later
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 4 of 6Not checkedPeople with high exposure to nighttime light had thickening of the left ventricle wall, reduced space inside the chamber, signs of reduced flexibility of the heart muscle, and changes in the right ventricle and left atrium.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 5 of 6Not checkedQi said this was the first study of its kind and that higher levels of light at night were linked to cardiac remodeling, which he described as a response to chronic stress or injury that can ultimately weaken the heart and lead to heart failure.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 6 of 6Not checkedAn accompanying editorial said clinicians should ask about sleep environment and night-shift work, and that reducing light pollution could be a public health strategy for cardiovascular health.View evidenceHide evidence
