First, I am biased against Finish studies, maybe unfairly, because of the so-called "beta caratene" link to lung cancer, that Yale Researchers later debunked.. using the same data. There was really no such link between beta caratene and lung cancer, as a review of the entire set of data showed, but the damage had been done because the first finding made news, the correction didn't.
Back to this apparently favorable study. It claims to be based on blood plasma levels. This is good/terrific!
From the abstract, this study seems to be indicating that your risk of having a heart attack, is 2 to 3 times higher, if your blood plasma vitamin C is low.
Added, and this illustrates another "technique" used to damn nutrients... If this was a drug, instead of 2.5 times, we'd see a 250% higher risk!

"Results: Over 196 713 total person-years (average follow-up: 9.5 y), 448 incident strokes occurred. In a Cox proportional hazards model, persons in the top quartiles of baseline plasma vitamin C concentrations had a 42% lower risk (relative risk: 0.58; 95% CI: 0.43, 0.78) than did those in the bottom quartile, independently of age, sex, smoking, body mass index, systolic blood pressure, cholesterol, physical activity, prevalent diabetes and myocardial infarction, social class, alcohol consumption, and any supplement use. Similar results were obtained after exclusion of persons with illnesses ,

, and persons with a history of early strokes during the initial 2 y of follow-up."https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3447163/
What a low plasma level!
" After adjustment for intake of vitamin C from food, plasma AA among those who took vitamin C supplements was further elevated by 3.5±20, 14.8±16, 10.2±16, and 19.7±15 μmol/L across quartiles of vitamin C intake from vitamin C supplements (P-trend<0.001)."https://academic.oup.com/aje/article/144/5/501/66603
". In conclusion, the results indicate that high intakes and plasma levels of vitamin C and frequent consumption of vegetables may be protective against early mortality and mortality from heart disease. Am J Epidemiol 1996; 144: 501-11."http://www.sciencedirect.com/science/ar ... 5095056599
"Supplementation of otherwise healthy smokers for 4 weeks with 1000 mg ascorbate per day resulted in increased plasma ascorbate and reduced LDL oxidative susceptibility."https://link.springer.com/article/10.10 ... 55?LI=true
But positive, vitamin E too.https://link.springer.com/article/10.10 ... 55?LI=true
"We had hoped that it would be possible to perform a meta-
analysis of high-quality trials with vitamin C as a single
substance based on the criteria suggested in Table 3, but
have found that at this point this is not possible because
such trials have not been performed.
