High R wave as a risk factor for cardivoascular and all-cause mortality. A 45-year follow-up of 13 cohorts of the Seven Countries Study
2022, Journal of ElectrocardiologyCitation Excerpt :In another analysis run on the subset of the SCS made by the Italian cohorts, with a follow-up of 20 to 23 years, the standard 12‑lead QRS voltage sum, as a continuous covariate, was an independent positive predictor of sudden and not of non-sudden coronary deaths (also including heart failure and arrhythmia cases) even after adjustment for major coronary risk factors [10]. Interestingly, non-sudden deaths were predicted there but inversely by the Sokolow-Lyon index, a standard ECG parameter of left ventricular hypertrophy [10]. It may certainly be worthwhile to consider thus the need to repeat the present analyses by measuring R wave amplitudes as a continuous covariate rather than having just the dichotomous Minnesota Code 3.1 to detect an abnormality.
How the Seven Countries Study contributed to the launch and development of cardiovascular epidemiology in Italy. A historical perspective
2020, Nutrition, Metabolism and Cardiovascular DiseasesCitation Excerpt :Technology, statistics and research approach of epidemiology has probably influenced other research areas in Italy. For example, in connection with the first Cox proportional hazards models of the IRA study published in 1987–88 with, respectively, the 25-year all-cause mortality [57] and CHD mortality as end-points [58], and during the development of independent investigations on electrocardiographic predictors of sudden death [96,98], there was a direct contamination of separate discussions and ideas among involved Investigators. It ensued in the testing of Cox's model in experimental cardiology [103–105] whereby the incidence of ventricular fibrillation was predicted during acute left circumflex coronary artery ligation in anesthetized dogs.
