- Two main statins—rosuvastatin and atorvastatin—are equally efficient at lowering coronary heart assaults, strokes, and all-cause deaths, a brand new research has discovered.
- The findings point out that rosuvastatin lowers ldl cholesterol a bit greater than atorvastatin but additionally carries the next danger of creating diabetes and cataracts.
- Only a 3rd of the research’s individuals have been ladies, so their danger in taking these statins must be the topic of future analysis.
The two strongest statins prescribed for coronary coronary heart illness are rosuvastatin and atorvastatin. Both are equally efficient at lowering the probability of strokes, coronary heart assaults, and mortality, in response to a brand new research. The two medicine, nonetheless, differ in a few essential respects.
Rosuvastatin seems to do a greater job at reducing levels of cholesterol, however is related to an elevated danger of diabetes and cataracts.
Lowering LDL levels of cholesterol — “bad” ldl cholesterol — is a vital therapeutic purpose within the remedy of coronary coronary heart illness, and rosuvastatin could thus be the statin of selection for a lot of.
For individuals thought-about prone to diabetes, although, atorvastatin could present the safer choice.
The research concerned 4,400 individuals in a trial that was performed at 12 hospitals all through South Korea. Participants have been divided into two teams, every of which was administered both rosuvastatin or atorvastatin between September 2016 and November 2019. In the tip, 4,341 people accomplished the trial.
The imply age of individuals was 65, with a normal deviation of 10 years, and 27.9% have been ladies.
The research is revealed in The BMJ.
The major outcomes wherein researchers have been have been coronary heart attack, stroke, all-cause demise, and the necessity for coronary revascularization, wherein a person’s blood circulate to an space of the guts have to be restored. For all of those, the 2 statins carried out roughly equally.
About 1.5% of the rosuvastatin group and 1.2% of the atorvastatin group skilled coronary heart assaults. Approximately 1.1% and 0.9% of the 2 teams, respectively, skilled stroke. For 2.6% and a couple of.3% of each teams, researchers recorded all-cause deaths. Around 5.3% versus 5.2% of the teams wanted coronary revascularization.
The authors of the research have been additionally involved about security, monitoring incidents of new-onset diabetes, heart-failure hospital admissions, pulmonary thromboembolism or
The rosuvastatin group was extra seemingly, 7.2%, to develop sort 2 diabetes than the atorvastatin group, 5.3%. They have been additionally extra more likely to require cataract surgical procedure, 2.5% versus 1.5%.
“Although there were small differences between the two statins regarding diabetes and cataract, the differences were all statistically significant,” the research’s senior investigator, Dr. Myeong-Ki Hong, professor of cardiology on the Yonsei University College of Medicine, advised Medical News Today.
“In a head-to-head consideration of a patient’s medical profile and risk reduction strategies, it would likely be a factor,” mentioned Dr. Jayne Morgan, heart specialist and govt director of well being and neighborhood training on the Piedmont Healthcare Corporation in Atlanta, GA, who was not concerned within the research.
Prof. Hong famous that these two outcomes weren’t completely shocking, as an earlier research had additionally noticed a rise in diabetes with rosuvastatin, and one other famous a rise in cataract surgical procedures.
On the plus aspect, for the rosuvastatin group, their LDL levels of cholesterol have been decrease than the atorvastatin group, 1.8 to 1.9 mmol/L, respectively.
“Careful interpretation is required toward our study findings. Our study does not support [a] certain type of statin over the other statin. We want to emphasize that while the cardiovascular benefits between the two potent statin types were comparable, each statin has different strengths and weaknesses regarding LDL-cholesterol lowering, new-onset diabetes, and cataracts.”

Statins, initially from fungi, are extensively prescribed for reducing ldl cholesterol and stopping coronary coronary heart illness.
Their use has skyrocketed 149% since 2013, in response to a 2023 research. It is
“Statins can both reduce and retard the deposition of atherosclerotic plaques in the coronary arteries. This decreases buildup and the likelihood of occlusion of critical coronary arteries feeding oxygen to the heart, and therefore decreases the risk of heart attacks.”
— Dr. Jayne Morgan
Exactly how statins preserve arteries wholesome isn’t properly understood, though a
The research asserts that statins forestall tightly bundled DNA, known as chromatin, in endothelial cells that line blood vessels from being loosened by a protein, YAP, that might in any other case result in modifications in gene expression that trigger them to rework into much less versatile and useful mesenchymal cells.
“Diabetes itself can lead to structural changes in the lens of the eye that can then lead to cataracts,” mentioned Dr. Morgan. “This is because of the duration of exposure of the eye to high levels of blood glucose/ sugar over time.”
“In fact, diabetic retinopathy is a well-known complication of diabetics that can cause blindness. While cataracts are an inevitable part of aging for many, diabetics have an accelerated development of cataracts at a younger age that leads to a build-up of deposits on the eye’s lens.”
— Dr. Jayne Morgan
“Our study provides insights for the importance of meticulous monitoring and appropriate lifestyle interventions to mitigate the risk of new-onset diabetes or cataracts in patients with coronary artery disease when using rosuvastatin over atorvastatin,” Prof. Hong mentioned.
Dr. Morgan mentioned some limitations within the research give her pause. First, it contains solely East Asian individuals from Korea, with no illustration of different racial teams.
She additionally harassed that solely a 3rd of the individuals have been ladies and their ages are unclear from the research.
“Elevated lipids are an established risk factor for heart disease. Heart disease is the number one killer of women worldwide, and the incidence of
Dr. Morgan additionally identified that the research additionally didn’t observe osteoporosis in menopausal ladies.
“Moreover, cholesterol-lowering drugs, and statins in particular, may have either a benefit — or a risk — to the menopausal woman of developing osteoporosis, depending on the dose,” she mentioned.
