Predictors of in-hospital mortality in octogenarian patients who underwent primary percutaneous coronary intervention after ST segment elevated myocardial infarction

Primary PCI in a nonagenarian: an uncommon predicament

Myocardial infarction in a nonagenarian is a morbid cardiac illness that can lead to significant mortality unless properly dealt with management aspects. Many comorbid or family-related issues might be part of holdbacks in management of such a group of patients. Hence, myocardial infarction in a nonagenarian where intervention is better treatment option forms an uncommon combination and has many preprocedural, periprocedural and postprocedural difficulties related to multiple issues. Here, we present a case of nonagenarian who presented with extensive anterior wall MI and was successfully dealt with primary percutaneous coronary intervention despite periprocedural and intraprocedural difficulties.

Association between vitamin D deficiency and heart failure risk in the elderly

AIMS

The aim of this study was to evaluate the association between vitamin D deficiency and risk of heart failure in elderly patients of cardiology outpatient clinics.

METHODS AND RESULTS

A cross-sectional study with an analytical approach was employed. Clinical data were collected from the elderly from August 2015 to February 2016. The dependent variable was the risk of heart failure; the independent variable was vitamin D deficiency; and intervening factors were age, gender, education, ethnicity, hypertension, diabetes mellitus, hypothyroidism, renal failure, dementia, stroke, dyslipidaemia, depression, smoking, alcoholism, obesity, andropause, and cardiac arrhythmia. To analyse the association between vitamin D deficiency and risk of heart failure, we used the bivariate logistic analysis, followed by analysis through the multivariate logistic regression model. Of the 137 elderly, the study found the following: women (75.9%); overweight (48.2%); obese (30.6%); increase in the index waist/hip (88.3%); dyslipidaemia (94.2%) and hypertension (91.2%); coronary artery disease (35.0%); and 27.7% with cardiac arrhythmia or left ventricular hypertrophy. Sixty-five per cent of the elderly were deficient in vitamin D. The risk of heart failure was significantly associated with vitamin D deficiency [odds ratio (OR): 12.19; 95% confidence interval (CI) = 4.23-35.16; P = 0.000], male gender (OR: 15.32; 95% CI = 3.39-69.20, P = 0.000), obesity (OR: 4.17; 95% CI = 1.36-12.81; P = 0.012), and cardiac arrhythmia (OR: 3.69; 95% CI = 1.23-11.11; P = 0.020).

CONCLUSIONS

There was a high prevalence of vitamin D deficiency in the elderly, and the evidence shows a strong association between vitamin D deficiency and increased risk of heart failure in this population.
