BACKGROUND: Physical exertion, anger, and emotional upset are reported to trigger acute myocardial infarction (AMI). In the INTERHEART study, we explored the triggering association of acute physical activity and anger or emotional upset with AMI to quantify the importance of these potential triggers in a large, international population. METHODS: INTERHEART was a case-control study of first AMI in 52 countries. In this analysis, we included only cases of AMI and used a case-crossover approach to estimate odds ratios for AMI occurring within 1 hour of triggers...

BACKGROUND: Higher concentrations of the apolipoprotein B (apoB) lipoproteins increase the risk of cardiovascular disease. However, whether the risk associated with apoB lipoproteins varies with age has not been well examined. METHODS AND RESULTS: We determined the associations for total cholesterol, low-density lipoprotein (LDL)-cholesterol (LDL-C), non-high-density lipoprotein-cholesterol (non-HDL-C), apoB, apolipoprotein A-I (apoA-I), and HDL-cholesterol (HDL-C) with myocardial infarction at different ages in 11 760 controls and 8998 myocardial infarction cases of the INTERHEART Study...

Cardiovascular disease (CVD) is a leading cause of death for both women and men. Common traditional risk factors for CVD, such as hypercholesterolemia, hypertension and smoking have a high prevalence in women and in some cases a greater health impact compared with men. Nevertheless, risk factors are treated less often and less aggressively in women than in men, partly due to decreased awareness on the part of public health opinion makers, patients and physicians. About seventy five percent of all coronary heart disease deaths among women could be avoided if CVD risk factors like hypercholesterolemia, hypertension and smoking are adequately treated...

BACKGROUND: Smokeless tobacco is consumed in most countries in the world. In view of its widespread use and increasing awareness of the associated risks, there is a need for a detailed assessment of its impact on health. We present the first global estimates of the burden of disease due to consumption of smokeless tobacco by adults. METHODS: The burden attributable to smokeless tobacco use in adults was estimated as a proportion of the disability-adjusted life-years (DALYs) lost and deaths reported in the 2010 Global Burden of Disease study...

India is experiencing an alarming rise in the burden of noncommunicable diseases, but data on the incidence of chronic kidney disease (CKD) are sparse. Using the Center for Cardiometabolic Risk Reduction in South Asia surveillance study (a population-based survey of Delhi and Chennai, India) we estimated overall, and age-, sex-, city-, and diabetes-specific prevalence of CKD, and defined the distribution of the study population by the Kidney Disease Improving Global Outcomes (KDIGO) classification scheme. The likelihood of cardiovascular events in participants with and without CKD was estimated by the Framingham and Interheart Modifiable Risk Scores...

Cardiovascular diseases are the leading cause of death in Latin America, with ischemic heart disease as the principal cause in most countries. Risk factors for cardiovascular disease are highly prevalent in the region, but there are international variations in the pattern and level of risk factors. Overweight and obesity are increasing. In the 2012 Mexican National Survey, overweight or obesity was found in 64.9% of men and 73% of women, and they were strongly associated with sedentarism. The most characteristic dyslipidemia abnormality in the region is low high-density lipoprotein cholesterol, followed by elevated low-density lipoprotein cholesterol and increased levels of triglycerides...

This article presents core epidemiological studies that establish the basis for cardiovascular prevention strategies. The results of the classic INTERHEART and INTERSTROKE studies that delineated population-attributed risk for myocardial infarction and stroke are described. Differences in the levels or types of prevention-primordial, primary, and secondary-lead to the concept that risk occurs on a continuum throughout life with great variability, beginning in infancy. Any meaningful and sustained reduction in cardiovascular risk must begin in childhood, as habits formed early in life have an impact for decades...

BACKGROUND: Although moderate alcohol use is associated with protection against myocardial infarction (MI), it is not known whether this effect is generalizable to populations worldwide. It is also uncertain whether differences in the pattern of alcohol use (and in particular heavy episodic consumption) between different regions negate any beneficial effect. METHODS AND RESULTS: We included 12 195 cases of first MI and 15 583 age- and sex-matched controls from 52 countries...

BACKGROUND: Less sleep time and snoring have been associated with cardiovascular disease (CVD) risk in Western populations; however, few studies have evaluated the different aspects of sleep duration and snoring frequency in relation to CVD, and this association has not been examined in China. The present study aimed to address the relation between sleep duration, snoring frequency and risk of acute myocardial infarction (AMI) in China population. METHODS: We conducted a hospital-based case-control study...

We assessed the association between tea consumption and acute myocardial infarction (AMI) using INTERHEART China data. Cases (n = 2909) and controls (n = 2947) were randomly selected and frequency matched by age and sex. Participants who drank tea ≥4 cups/d had a significantly higher risk of AMI than tea nondrinkers; odds ratio (OR) was 1.29 (95% confidence interval [CI]: 1.03-1.61) compared with tea nondrinkers. A similar trend was found in green tea drinkers; OR was 1.52 (95% CI: 1.13-2.05) in the participants who drank 3 cups/d and 1...

AIMS/HYPOTHESIS: Dyslipidaemia, a common feature of type 2 diabetes, is characterised by an increase in atherogenic particles, quantifiable through apolipoprotein B (ApoB) levels. Genetic studies of lipid levels have focused on Europeans; a study in South Asians could identify novel genes. METHODS: We tested 31,739 single nucleotide polymorphisms (SNPs) from ∼ 2,000 genes in 2,573 South Asians from the epidemiological arm of the Diabetes Reduction Assessment with Ramipril and Rosiglitazone Medication (DREAM) study (EpiDREAM) for association with ApoB and we tested two novel associations for replication in 1,181 South Asians from the INTERHEART case-control study...

BACKGROUND: Patients with increased numbers of cholesterol-depleted apolipoprotein B (apoB) particles frequently have multiple other abnormalities, which might confound the comparison of apoB and non-high-density-lipoprotein-cholesterol (non-HDL-C) as markers of cardiovascular risk. OBJECTIVE: We wanted to determine whether the superiority of apoB over non-HDL-C as a marker of cardiovascular risk in the INTERHEART study is due to such variables that act as confounders of the primary comparison...

BACKGROUND: People of South Asian origin suffer a high burden of premature myocardial infarction (MI). South Asians form a growing proportion of the Canadian population and preventive strategies to mitigate the risk of MI in this group are needed. Prior studies have shown that multimedia interventions are effective and feasible in inducing health behavior changes among the obese, smokers, and among those who are sedentary. OBJECTIVE: Among at-risk South Asians living in Canada, our objectives are to determine: (1) the feasibility of a culturally tailored multimedia intervention to induce positive behavioral changes associated with reduced MI risk factors, and (2) the effectiveness and acceptability of information communicated by individualized MI and genetic risk score (GRS) reports...
